Lanthanum Oxide Industrial Grade 99.9%

Lanthanum oxide is white orthorhombic system or amorphous powders. It is close to white powder of rhombohedral system or amorphous and hexagonal structure.  Lanthanum trioxide absorb carbon dioxide and moist in air, which turn into lanthanum carbonate. It is hard to dissolve in water, but dissolve in dilute inorganic acids.

Lanthanum Oxide

CAS No.: 1312-81-8 EINECS No.: 215-200-5 Molecular Formula: La2O3 Molecular Weight:325.82
Melting Point:2315℃ Boiling Point:4200℃ Density:6.51 Flash Point:4200

Applications

Lanthanum(III) oxide is mainly for production of special alloys, light-guide fibre, precision optical glass and high refraction optical fiber board, which is fit for camera, microlens, advanced optical instrument prism.

In ceramic industry, it use in producing ceramic capacitors, piezoelectric ceramic dopant and lanthanum oxybromide powder of X-ray luminescent materials.

Lanthanum trioxide doping in lithium oxide or zirconium oxide can apply to make ferrimagnetics. It can improve temperature dependence and dielectric properties of barium titanatestrontium titanate and other feroelectrics. It is also raw material for fiber optic device and optical glass.

La2O3 is raw material for lanthanum boride. It is also catalysts for many kinds of reaction.

Lead Chromate

Lead chromate is a chemical compound, a chromate of lead. It is used in some pyrotechnic compositions, especially delay compositions, as an oxidizer. Up to the late 1800s it was used to impart a bright yellow color to some types of candy. Lead(II) chromate and lead(II) carbonate were the most common lead-based paint pigments.

Properties Suppliers
Lead Monoxide

Lead monoxide is an inorganic compound. It is produced on a large scale as an intermediate in the conversion of lead ores, mainly galena into metallic lead. The consumption of lead, and hence the processing of PbO, correlates with the number of automobiles because it remains the key component of automotive lead-acid batteries. It is used extensively in manufacturing of lead glasses and ceramic glazes as well as in fine dinnerware. Other less dominating applications include the vulcanization of rubber and the production of certain pigments and paints. It is used in cathode ray tube glass to block X-ray emission, but mainly in the neck and funnel because it can cause discoloration when used in the faceplate. Strontium oxide is preferred for the faceplate. PbO is used in certain condensation reactions in organic synthesis.

Properties Suppliers
Lead Nitrate

Lead Nitrate is a granular white crystal powder with the chemical formula Pb (NO3)2. It is produced by dissolving metallic lead in aqueous nitric acid. Lead nitrate is the raw material for the pigments for lead paints, lead compounds, nylon fiber stabilizer, textile mordant, and leather tanning agent.
