Crowns (also known as caps) are porcelain restorations placed on an existing tooth to correct massive decay, wear, or breakage in a tooth. They support your existing tooth structure so that you may keep your teeth. Crowns are made with a variety of materials such as gold (considered the strongest material), porcelain (used to maintain the natural look of your smile), and porcelain to metal (porcelain supported by metal to make it stronger). Depending on your goals and the functional needs of your smile ...
Porcelain and porcelain enamel may have different bases, the former clay and the latter cast iron or stainless steel, but you can repair small scratches on the glass-like glaze or coating in the same way. When the scratch hasnt fully penetrated the outer surface, clean the porcelain before buffing out the scratch. If the base metal or clay is exposed, clean and then replace the missing coating with two-part epoxy or a porcelain repair product.. ...
RHs Chinese Porcelain Classic Coupe Cereal Bowl (Set of 4):China was the birthplace of porcelain more than 2,000 years ago, and its legacy of producing the world's finest porcelain continues today. We went back to the source, seeking out China's most esteemed artisans to create our dinnerware collection – defined by perfect proportions, clean lines and distinctive color glazing. The pieces are individually hand dipped, an artisanal process that creates organic variations in color that are unique to each piece and every place setting.

Historical Note. The use of the basic materials of porcelain was known to the Chinese for many centuries before the secret was discovered by European potters, and native tradition, which has long revered porcelain as a precious and half-magical substance, places the beginning of the art in the remote and legendary past. However, no known fragment of vitrified ware has descended to us from very ancient times and it is not until the beginning of the Sung dynasty in the tenth century of the Christian era that there is tangible proof of the manufacture of any substance approaching porcelain, as we define it. From that period onward through the succeeding Yuan and Ming dynasties the art has been constantly in process of development and many remarkable wares of widely varying types have been produced, until, in the seventeenth and eighteenth centuries, under the last, or Ching dynasty, porcelain in China reached a state of excellence admitting of no improvement and marking the culmination of an art ...

The thermal expansion behavior of $MTi_2P_3O_{12}$ compounds with $M = Na^+, Cd_{0.5}^{2+}, and La_{0.33}^{3+}$ has been studied by high temperature X-ray diffraction. The difference in the anisotropic axial thermal expansion coefficients drastically varies for cations with varying charges but with similar sizes. The thermal expansion in this family of compounds seems to be essentially due to $M-O$ bond expansion. A new compound $La_{0.33}Ti_2P_3O_{12}$ with hexagonal structure $(a = 8.295$\AA and $c = 22.426$\AA) is reported.. ...
Porcelain will not chemically bond with gold by itself. There needs to be a mix of trace elements in the composition of the alloy to allow the formation of an oxide layer on its surface, which then bonds the porcelain to the metal. The three oxide-forming elements are iron, indium and tin. Porcelain is, itself, made of metal oxides. Thus it will bind with the oxides on the surface of the gold framework.. The necessity for the formation of metal oxides on the surface of the underlying casting means that ions from the metal casting will mix with the porcelain, potentially affecting the color, reflective properties and translucency of the finished product. Thus the porcelain must be formulated to overcome these effects.. Porcelain melts at high temperatures (between 850°C and 1350°C depending on the type of porcelain used). It is applied as wet powder over the metal framework, and baked, or fired in order to fuse the powder particles together. This means that the metal substructure upon which the ...

The temperature dependence of lattice parameters a in the quasiperiodic plane and c in the periodic direction of decagonal Al70.7Co13.3Ni16.0 was probed using X-ray powder diffraction in the temperature range 15-300 K. Both parameters were fitted by means of positions of 22 Bragg reflections for each temperature. Temperature dependences were modelled best by second order polynomials leading to linear thermal expansion coefficients α(T) = 8.1(33) · 10-7K-1 + 3.9(2) · 10-8K-2 T in the quasiperiodic plane and γ(T) = 1.7(6) · 10-6K-1 + 3.8(3) · 10-8K-2 T in the periodic direction, respectively. Thus we found the anisotropy ratio γ(T)/α(T) to decrease with increasing temperature from 1.60 (at 15 K) to 1.05 (at 300 K). Besides pecularities around 150 K indicating an intermediate phase formed by superordering, we observed deviations from the general smooth course between 15 K and 50 K for both lattice parameters. ...

In this study, thermal stresses analysis of ZrO2 insulation coatings on Cr-Ni substrate during the cooling process was investigated. A transient thermal analysis was performed using finite element method (FEM) via ANSYS software. The temperature versus the time curve obtained from FEM solution was controlled with the temperaturetime diagram measured by a thermocouple. The results obtained from the numerical calculations were improved by the experimental measurement. Additionally, residual stresses were calculated by FEM solutions and they were compared in different points. The compressive and tensile stresses occurred in ZrO2 coating and Cr-Ni substrate owing to the different thermal expansion coefficients in each material, respectively.
The thermal expansion coefficients associated with the C49 and C54 crystal directions have been determined by in situ x-ray diffraction analysis of Ti film annealing deposited on Si substrates. Evidence of a clear anisotropy in the C49 coefficients has been obtained: the α[sub b] is considerably smaller than α[sub a] and α[sub c]. The volume expansion is larger in C54: this contributes to reduce to 1.6% at the transformation temperature, the observed 2.0% volume difference at 300 K. The magnitude of the volume discontinuity during transformation is an indication for a first-order transition. © 2001 American Institute of Physics ...
In November 2010, a Chinese vase unearthed in a suburban semi in Pinner sold at auction for 43 million - a new record for a Chinese work of art. Why are Chinese vases so famous and so expensive? The answer lies in the European obsession with Chinese porcelain that began in the 16th century. In this documentary Lars Tharp, the Antiques Roadshow expert and Chinese ceramics specialist, sets out to explore why Chinese porcelain was so valuable then - and still is now. He goes on a journey to

Taken from his latest album, Strange Weekend, Unless You Speak From The Heart is the latest single to be dropped. For reference, Im a fan of Porcelain Raft, but I wasnt really feeling this one. Its in sync with his style enough, the 4/4 simple beats, the repetitive chord progression and the atmospheric reverb over the airy synth. However, I didnt think it had that much flavour or stand out moments to make it truly memorable. There is a slight hint that Mauro Remiddis trying to be more consistent as a musician, and appeal more to people who like Yeasayer and other mainstream downbeat electro artists like that, but in doing that, I dont feel like Im listening to a Porcelain Raft track. As is the way with a lot of debut proper releases from artists, they often decrease in quality, and seem very clean and very professional. Unfortunately this just feels a bit over produced and plain. Even the vocals are repetitive and uncaptivating. Sadly not a fan of this one. It was okay, but nothing ...

Porcelain tile is made up of 50% feldspar and is fired at a much higher temperature than regular ceramic tile. This makes porcelain tile much harder and more dense than other tile products. Because of its highly durable make-up, porcelain is more resistant to scratches and can withstand temperature extremes. Also, because porcelain is non-porous, its very stain resistant, has very low water absorption ratings (Less than 0.5%) and thus can be used for interior and exterior applications as well as heavy-use and commercial areas. Finally, because porcelains color goes all the way through, small scratches or chips are less noticeable. Pressing ...
