  • Talc
  • Talcum powder is made from talc, a mineral made up mainly of the elements magnesium, silicon, and oxygen. (cancer.org)
  • When talking about whether or not talcum powder is linked to cancer, it is important to distinguish between talc that contains asbestos and talc that is asbestos-free. (cancer.org)
  • Whether you want to reduce shine during the day, or create a smooth, even base in the morning, this wet/dry talc-free powder will be perfect for you. (nuskin.com)
  • produces
  • Cold compaction after dehydrogenation of the powder, followed by either vacuum hot pressing (in this case the dehydrogenation process can be bypassed as hydrogen is removed under vacuum) or HIP and a final vacuum anneal, produces powders with hydrogen below 125 ppm. (wikipedia.org)
  • mechanical
  • This short course will outline the principles and methods for characterising the chemical, physical and mechanical properties of powders at length scales ranging from molecular level to single particles and to bulk levels. (rsc.org)
  • Definition
  • As with most colours, there is no absolute definition of its exact hue, but according to Etymology Online, powder blue originally referred in the 1650s to powdered smalt (cobalt glass) used in laundering and dyeing applications, and it then came to be used as a colour name from 1894. (wikipedia.org)
  • Although smalt itself is a deep, dark blue hue, powder blue is nowadays depicted as more of a pale cobalt blue as illustrated by the examples below, which show powder blue as defined by British and Australian Standards for paint colours along with an example of one manufacturer's actual Powder Blue paint, and a consensus definition produced by an online colour names survey in which 140,000 people took part. (wikipedia.org)
  • particles
  • It has been suggested that talcum powder might cause cancer in the ovaries if the powder particles (applied to the genital area or on sanitary napkins, diaphragms, or condoms) were to travel through the vagina, uterus, and fallopian tubes to the ovary. (cancer.org)
  • Iron powder is formed as a whole from several other iron particles. (wikipedia.org)
  • A powder is an assembly of dry particles dispersed in air. (wikipedia.org)
  • A powder can be free-flowing if the particles do not stick together or cohesive if the particles cling to one another to form aggregates. (wikipedia.org)
  • However, if powders with particles of different size, density or shape are mixed the segregation can occur. (wikipedia.org)
  • colour
  • The colour powder blue . (wiktionary.org)
  • So what does powder mean when it is related to a colour? (usingenglish.com)
  • It can be seen that although the sources differ on how pale or saturated a colour "powder blue" is, they broadly agree as to its hue. (wikipedia.org)
  • There is also a recorded use of powder blue as a colour name in English in 1774, however the sources offer more than one possible colour of this name, including a blue-grey and a dark unsaturated blue. (wikipedia.org)
  • This is the colour which is displayed by web browsers if "powder blue" is specified in HTML or CSS code. (wikipedia.org)

  • moisture
  • As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping to prevent rashes. (cancer.org)
  • fine
  • The papers intimate at, but don't make clear, a potential explanation: While the bacteria itself is garden variety, the powder in which it was carried was very fine and easily dispersed--in other words, weapons grade. (slate.com)
  • These are sterilised in boiling water and then milled into a fine powder using stainless steel grinding discs or by milling with small porcelain balls in moist conditions. (wikipedia.org)
  • size
  • 2fg: The actual grain size of the powder is smaller than that of the 1fg powder. (angelfire.com)
  • between 100 and 300 µm is size, with good packing and flow characteristics, making the powder ideal for high quality, near net shapes produced by HIP, such as aviation parts and porous coatings on hip prostheses. (wikipedia.org)
  • Metal injection moulding (MIM) otherwise known as powder injection moulding is a well-established and cost-effective method of fabricating small-to-moderate size metal components in large quantities. (wikipedia.org)
  • possible
  • Many studies in women have looked at the possible link between talcum powder and cancer of the ovary. (cancer.org)
  • The possible presence of contaminants makes these powders unsuitable for use in critical aircraft applications. (wikipedia.org)
  • Metal
  • Powders can be produced by the blended elemental technique or by pre-alloying and then consolidated by metal injection moulding, hot isostatic pressing, direct powder rolling or laser engineered net shaping. (wikipedia.org)
  • It is derived from the method plastic injection moulding, whereby mixing of a metal powder with a polymer binder forms the feedstock, which is then injected into a mould, after which the binder is removed via heat treatment under vacuum before final sintering. (wikipedia.org)
  • either
  • Powder diffraction data are usually presented as a diffractogram in which the diffracted intensity, I, is shown as a function either of the scattering angle 2θ or as a function of the scattering vector length q. (wikipedia.org)
  • Brattle, who had not obviously sided with either Loyalists or Patriots, notified Governor Gage in a letter dated August 27 that the provincial ("King's") powder was the only supply remaining in that storehouse, as the towns had removed all of theirs. (wikipedia.org)
