Thallium bromide is yellowish white crystalline powder, which is a thallium salt. It is faintly soluble in water and soluble in ethyl alcohol, but insoluble in acetone. Thallium(I) bromide is stable at room temperature and pressure. It does not resistance to heat. Thallium chloride, thallium nitrate or thallium sulfate solution is the raw material.
Thallous bromide is raw material for production of medicine.
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(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.
Thallium sulfate is white crystalline powder, which is a thallium salt. It is easily soluble in dilute acid and water. Thallium metal is raw material for thallium(I) sulfate.
Thallous sulfate used to be rodenticide. Now it mainly apply to Tl+ source in laboratory. Thallium(I) sulfate apply to analytical reagent and pharmacy industry. It is also raw material for other thallium salts as thallium(I) hydroxide, thallium carbonate, thallium bromide, thallium iodide and so on.
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(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 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(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.
Ytterbium chloride hexahydrate is white crystalline granules, which is a rare earth salt. It tend to dissolve in water and disolve in absolute ehtyl alcohol. When at 180℃, it lose six water molecule. Ytterbium oxide is the raw material.
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(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.
Zinc Sulfide Crystal Leftover
Zirconium Oxalate Powder
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.
