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

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 titanate, strontium 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.

Lanthanum Sulfide Industrial Grade 99%

Lanthanum sulfide is yellow crystal powder, which is a kind of rare earth sulfide powder. Sulfur and lanthanum metal are the raw material.

Lanthanum Sulfide

Applications

Lanthanum(III) sulfide mainly apply to optical materials and ceramics.

Magnesium Sulfide Industrial Grade 99%

Magnesium sulfide is colorless to brown crystal powder, which is sulfide of magnesium. It is of sodium chloride type structure and the chemical property is similar to other  ionic type sulfide compounds as sodium sulfide, barium sulfide and calcium sulfide. Magnesium metal and pure sulfur are the raw materials.  It dissolve in diluted hydrochloric acid, however MgS crystal react with water slowly.

Magnesium Sulfide

Applications

Magnesium sulphide can apply to do desulfurization for iron and steel and making fluorescent powder.  It can apply as a semiconductor with wide band gap.

Manganese Carbide Industrial Grade 99%

Manganese carbide is black crystal powder, which is metal carbide.  It is soft crystal solid or bright needle-like crystal. Mn3C is insoluble in concentrated sulfuric acid and nitric acid, how it can be decomposed by water or dilute acid to form manganese hydroxide, hydrogen and hydrocarbon. It burns in oxygen quickly. Mn3C tend to react with fluorine and chlorine. Manganese powder is the raw material.

Manganese Carbide

Applications

Manganese carbide applies to produce manganese hydroxide, hydrogen, hydrocarbon and additive of powder metallurgy.

Mercury Telluride Industrial Grade 99%

Mercury telluride is black crystal, which is available in form of cylinder, rod, ingot, sheet,  pieces, granule and powder. It is stable under room temperature and pressure. HgTe is insoluble in water. There are two production methods, zone melting and Bridgman method. Mercury and telluriumare the raw materials.

Mercury Telluride

Applications

Mercury telluride is mainly for producing infrared detector. HgTe is also raw material for growing zinc mercury telluride films.

Neodymium Oxide Industrial Grade 99.9%

Neodymium oxide is kind of light blue rare earth oxide powder, which turns dark blue after damping. Industrial grade is brown. It tends to damp and absorb carbon dioxide in air. Neodymium trioxide is insoluble in water, but soluble in dilute acid. When heating in air, it turns out high order oxide of neodymium.

Neodymium Oxide

Applications

Neodymium trioxide mainly apply as colorant of glass and ceramic. It is also raw material for metal neodymium and strong magnetic Nd-Fe-B.

Adding 1.5%~2.5% nano neodymium oxide in magnesium alloys or aluminum alloys can enhance their high-temperature property, gas tightness and corrosion resistance. They are widely used as aerospace material.

Nano yttrium oxide aluminum garnet with doping nano neodymium oxide shots short wave laser beam. It widely apply to 10mm max thin material welding and cutting. In medical treatment, it can replace scalpel to do extraction or disinfect wound.

Neodymium trioxide can be additive for rubber goods.

Organic Germanium Industrial Grade 99%

Organic germanium includes synthetic organic germanium, natural organic GE and biological organic Ge. The synthetic one is carboxyethyl germanium sesquioxide that is Ge-132, spirogermanium, Furan germanium derivates and other antiviral, anti-inflammatory and anticancer organic Ge. It is compound that has wide pharmacologic action, but if over dose, it cause acalcerosis. Natural organic Ge is extracted from natural plants, which gets no toxic and side effect to human body. Biological organic Ge is planting germanium compounds into biological body, for example yeast, germ, macro fungi, vegetable and so on.  Ge-132 is short of (GeCH2CH3COOH)2O3

Organic Germanium

Ge-132 applies to functional health food, medicine, cosmetics and so on.
