Thallium Nitrate Industrial Grade 99.9%

Thallium nitrate is white crystalline particle, which is a thallium salt. It decompose at 260℃, which is soluble in water and acetone, but not soluble in ethyl alcohol. Thallium metal is the raw material

Thallium Nitrate

Applications

Thallium(I) nitrate is for doing quantitative analysis of coexisting chlorine, bromide and iodine. It is also raw material for optical (waveguide) fibre material.

Thallous nitrate is a kind of analytical reagent, which is also raw material for thallium test paper and maritime marker.

Titanium Disulfide Industrial Grade 99%

Titanium disulfide is yellow crystalline powder with metallic lustre. It is stable at room temperature, further stable to water, dilute sulfuric acid and hydrochloric acid. However  nitric acid and sulfuric acid can resolve it and separate out sulfur. It has layers structure and every layer include S-Ti-S interlayer, between the interlayer contact by weak van der waals force. Titanium wire and sulfur or titanium tetrachloride and hydrogen sulfide are the raw material.

Titanium Disulfide

Applications

Titanium(IV) sulfide is ideal non-stoichiometric compound. It gets prospect in energy storage device or battery. Lithium can inset layer of titanium sulfide and form intercalation compound LiTiS2 formulation that continues change between x=0-1. It decides it is non-stoichiometric compound.

Tungsten Disulfide Industrial Grade 99%

Tungsten disulfide is gray fine particles or nano powder. It is a metal sulfide, which has property of semiconductor and diamagnetism. It is insoluble in water and alcohol, however dissolve in acid mixture of nitric acid and hydrofluoric acid and molten alkali. Tungsten(IV) sulfide is table at room temperature and pressure. Tungstic acid or tungsten is the raw material.

Tungsten Disulfide

Applications

Tungsten(IV) sulfide is a new solid lubricant, which apply to lubricate at high temperature, high pressure, high load and high vacuum condition. When it adds in engineering plastics, self-lubricating parts turn out.

When mix it with some volatile solvent and spraying in metal surface, it can improve the service life of mould in impact forging and degree of finish of workpieces.

Yttrium Nitrate Industrial Grade 99.99%

Yttrium nitrate hexahydrate is white crystalline granular, which is a rare earth salt. It is stable at room temperature and pressure. Yttrium(III) nitrate hexahydrate lose three water molecular at 100℃. It tend todeliquesce and dissolve in water, which also dissolve in ethyl alcohol and acetate. Yttrium trioxide is the raw material.

Yttrium Nitrate Hexahydrate

Applications

Yttrium(III) nitrate is a scientific reasearch reagent. It get wide applications in various fluorescent powder, high quality refractory matter, artificial stone laser crystal, superconducting materials, electronic industry and many cutting edge applications.

gallium sulfide Industrial Grade 99.99%

Gallium sulfide includes digallium trisulfide and gallium(II) sulfide, which are minor metal sulfides. Gallium(III) sulfide is white powder, however gallium(II) sulfide is yellow crystal. Ga2S3 is stable at room temperature and pressure. In air it slowly release hydrogen sulfide and turns into gallium trioxide, but quickly in water. Ga2S3 react with nitric acid to form hydrogen sulfide and sulfur and Ga3+ ion solution left. It dissolve in concentrated lye because it turns into gallium acid ion (IV). GaS sublimate at 900~1000℃ and decompose when higher than melting point. When heating in air, it release SO2. Processing it with 15% boilin acetic acid release hydrogen sulfide, which react with bromine violently. Gallium metal is raw material for GaS and Ga2S3.

Gallium Sulfide

indium tin alloy Industrial Grade 99.9%

Arsenic Trioxide Industrial Grade 99.99%

Arsenic trioxide is odorless white powder, which is most marketable arsenic compound and main start raw material for arsenic chemicals. It is faintly soluble in water and soluble in acid and alkali. The highest purity is 99.999%.

Arsenic Trioxide

Applications

Arsenia is mainly for refining of arsenic metal, which is also raw material for melting arsenic alloys and produce semiconductors. It uses as clarifying agent and decolorising agent in glass industry, which improve transparency of glass products.

In farming, arsenic(III) oxide apply as sanitizer and rust remover for insect disease prevention, which is also raw material for insecticidal pesticide containing arsenic.

Arsenic oxide use to produce coating and dyestuff. It is also kind of chemical reagent as standard reagent, reducing agent and absorbent of chlorine.

As2O3 get applications in desulfuration, anticorrosion of wood, antiscale of boiler, ceramic,  enamel, lether preservative and medicine.
