Holmium Fluoride Industrial Grade 99.5%

Holmium fluoride is yellow solid which is existed with both of  hexagonal crystal and orthogonal crystal. It is rare earth metal fluoride. It is insoluble in water and dilute acid. HoF3 is stable at room temperature and pressure. Holmium sulfate solution is the raw material.

Holmium Fluoride

Purity: Ho/RE 99.5% 2N5

Indium Fluoride Industrial Grade 99.99%

Indium fluroide is is white powder, which is minor metal fluoride. InF3 in 100g water dissolve with 0.04g. If reducing indium trifluoride, InF2 got, however it is easy to hydrolyze. There is also indium(III) fluoride trihydrate. Indium powder is the raw material.

Indium Fluoride

Applications

Indium trifluoride is raw material for non-oxide glasses. It is also catalyst for the addition of trimethylsilyl cyanide (TMSCN) to aldehydes to form cyanohydrins.

Indium Phosphate Industrial Grade 99.9%

Indium phosphate is dark gray crystalline powder, which is a kind of indium salt. It loses crystalline water at 350℃ and forms indium pyrophsophate. However it turns out amorphous indium phosphate at 640℃. But it decompose at 1800℃. InPO4 tend to compound with alkali metals and forms  double salt. It is hard to dissolve in water. Indium hydroxide is the raw material

Indium Phosphate

Applications

Indium phosphate is additive to special glass.

Samarium Hydride Industrial Grade 99.9%

Samarium hydride is rare earth metal hydride powder.

Samarium Hydride

Purity: Sm/RE 99.9% 3N

Particle size:-100mesh, -200mesh

Tantalum Pellets Industrial Grade 99.9%

Tantalum metal is silvery gray metal of body centered cubic structure, which is extremely hard and ductile. It mainly exist in tantalite with niboium.  It is available in powders, sheets, wires, ingots, granules, foils and sputtering targets. Ta resist corrosion from strong acid, especially to sulfuric acid.

CAS No.: 7440-25-7 EINECS No.: 231-135-5 Molecular Formula: Ta Molecular Weight: 180.948
Melting Point: 3000℃ Boiling Point: 5429℃ Density: 16.6

Tantalum metal can replace stainless steel in equipment that making various inorganic acids, which have tens times life longer than stainless steel. It can replace noble metal platinum in industries as chemical engineering, electronic and electric.

Tantalum powder process into electrolytic condenser. It forms stable anode oxide film in acid electrolyte. It is also raw material for making transmitting tubes and electric tube parts.

Tantalum can easily process into other shapes, so it act as supplied accessories, heat shield, heater and cooling fin in high temperature vacuum furnace.

Tantalum is raw material for alloys as Ta-W, Ta-W-Hf, Ta-Hf.

Terbium Hydride Industrial Grade 99.99%

Terbium hydride is black or brown lump solid, which is rare earth hydride. It react with water violently.

Terbium Hydride

Purity: Tb/RE 99.99% 4N

Particle size: -100mesh, -200mesh
