La2O3-Ne2O3-Pr6O11 Ternary Oxide Blend
A precisely blended mixture of lanthanum oxide (50%), neodymium oxide (30%), and praseodymium oxide (20%), engineered for optical glass doping where lanthanum predominates. Classified under HTS 2846.90.20.05 as a rare-earth oxide mixture excluding cerium oxides with lanthanum as the primary metal. Ideal for high-refractive index glass production.
Lanthanum-Dominant Rare Earth Oxide Mixture
A chemically defined mixture of rare-earth oxides where lanthanum oxide (La2O3) is the predominant component, typically containing 40-60% lanthanum oxide alongside smaller amounts of neodymium, praseodymium, and cerium oxides. This product falls under HTS 2846.90.20.05 as it is a mixture of rare-earth oxides (excluding cerium oxides as predominant) with lanthanum as the main metal. Used primarily in ceramics, glass polishing, and as a precursor for catalysts.
High-Purity Lanthanum-Rich Mischmetal Oxide
Refined oxide mixture from mischmetal processing with lanthanum oxide at 55%, didymium oxides (Nd/Pr) 35%, and traces of samarium/gadolinium, excluding cerium. HTS 2846.90.20.05 applies to such lanthanum-predominant rare-earth oxide mixtures used in hydrogen storage alloys and phosphors.
Didymium Oxide with Lanthanum Enrichment
Enriched didymium oxide where lanthanum content selectively increased to 52% (Nd 30%, Pr 15%, others 3%), used in fiber optic amplifiers, fitting HTS 2846.90.20.05 for lanthanum-predominant rare-earth oxide mixtures.
