  • oxygen
  • Lanthanum also reacts with oxygen in the air, especially if the air is moist. (encyclopedia.com)
  • It is also common of LaCoO3 to be utilized with either dopants or exhibit oxygen non-stoichometry where it may assume the structure La1−xA'xCo1−yB'yO3±𝛿 where 𝛿 is some small quantity making this class of perovskites extremely versatile for catalysis, one such commonly utilized material is lanthanum strontium cobalt ferrite otherwise known as LSCF. (wikipedia.org)
  • Lanthanum manganite is formed in the perovskite structure, consisting of oxygen octahedra with a central Mn atom. (wikipedia.org)
  • formula
  • Lanthanum gallium silicate (referred to as LGS in this article), also known as langasite, has a chemical formula of the form A3BC3D2O14, where A, B, C and D indicate particular cation sites. (wikipedia.org)
  • La2O3
  • 3 B2O3 + La2O3 → 2 La(BO2)3 When this 1:3 reaction is mixed into a glass composite, the high molecular weight of the lanthanum causes an increase of the homogeneous mixture of the melt which leads to a lower melting point. (wikipedia.org)
  • gallium
  • In this material, lanthanum occupied the A-sites, gallium the B, C and half of D-sites, and, silicon the other half of D-sites. (wikipedia.org)
  • The glass forming ability of gallium(III) sulfide and lanthanum sulfide was discovered in 1976 by Loireau-Lozac'h, Guittard, and Flahut. (wikipedia.org)
  • This family of chalcogenide glasses, referred to as gallium lanthanum sulfide (Ga-La-S) glasses, have a wide region of glass formation centred about the 70Ga2S3:30La2S3 composition and can readily accept other modifiers into their structure. (wikipedia.org)
  • phosphate
  • Lanthanum is used to treat hyperphosphatemia (too much phosphate in the blood) in patients with end stage kidney disease who are on dialysis. (drugs.com)
  • Lanthanum prevents the body from absorbing phosphate, allowing it to be removed from the body. (peacehealth.org)
  • manganites
  • The longer papers consider radio-frequency electrodynamic properties of bulk lanthanum manganites, sinter-alloying and properties of manganese steels, surface treatment effects on bulk material fatigue resistance, developing controllable chemical synthetic routes to elemental selenium and some metal chalcogenides as bulk materials and thin films, and unusual properties of laser-processed strontium ruthenates.

  • LaAlO3
  • The interface between lanthanum aluminate (LaAlO3) and strontium titanate (SrTiO3) is a notable materials interface because it exhibits properties not found in its constituent materials. (wikipedia.org)
  • naturally
  • Naturally occurring lanthanum (57La) is composed of one stable (139La) and one radioactive (138La) isotope, with the stable isotope, 139La, being the most abundant (99.91% natural abundance). (wikipedia.org)
  • Naturally occurring lanthanum consists of one stable isotope ( 139 La) and one radioactive ( 138 La) isotope, with the stable isotope, 139 La, being the most abundant (99.91 percent natural abundance). (newworldencyclopedia.org)
