Vanadium Sulfide 99

Vanadium Sulfide is a kind of metal sulfides. It is also vanadium(III) sulfide. It is grey powder. 

nitric acid >55-56%

Nitric acid is a colorless to yellow or red liquid sometimes fuming reddish brown vapors with a suffocating odor. Nitric acid is soluble in water with release of heat. Nitric acid is corrosive to metals or tissue. Nitric acid will accelerate the burning of combustible materials and Nitric acid may even cause ignition upon contact with combustible material. Nitric acid is fully soluble in water and may react violently upon contact with water with the evolution of heat, fumes and spattering. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects

4-Methoxybenzophenone

4-Methoxybenzophenone is used in the field of fine and speciality chemical.

4-Nitrophthalonitrile

4-Nitrophthalonitrile is used as an intermediate for the synthesis of corrosion inhibitors, medicines (Candesartan) and agrochemicals.

CYANEX 272 Extractant

CYANEX 272 Extractant has proven to be the reagent of choice for the separation of cobalt from nickel from both sulfate and chloride media. It is now being used to produce a major portion of the world’s cobalt. CYANEX 272 Extractant is totally miscible with common aromatic and aliphatic diluents, and is extremely stable to both heat and hydrolysis.

CYANEX 923 Extractant

Cytec Surface Specialties Germany GmbH is a supplier of CYANEX 923 Extractant which is a liquid phosphine oxide and has potential applications in the solvent extraction recovery of both organic and inorganic solutes from aqueous solution, e.g. carboxylic acids from effluent streams and the removal of arsenic impurities from copper electrolytes. Buy CYANEX 923 Extractant which exhibits a separation factor in ethanol/water solutions near the maximum useful limit for recovery from continuous fermentation broths, typically containing 5% ethanol.

SODIUM HYDROSULFITE

Sodium dithionite (also known as sodium hydrosulfite) is a white crystalline powder with a weak sulfurous odor. It is the sodium salt of dithionous acid. Although it is stable under most conditions, it will decompose in hot water and in acid solutions. 

Silver Nitrate 99.9%

Silvery sulfide is light ash black heavy powder, which is noble metal sulfide. It is insoluble in water and ammonium hydroxide, however soluble in nitric acid, sulfuric acid and alkaline cyanide solutions. β-Ag2S is ash black orthogonal crystal with relative density 7.326, which turns into α-Ag2S at 175℃. α-Ag2S is black cubic crystal with relative density 7.317 and melting point 825℃. Concentrated H2SO4 can transform Ag2S into silver sulfate and sulfur. Disilver sulphide is stable at room temperature and pressure, but it turns out filiform silver metal when heating above 350℃ in vacuum. If heating in air directly, silver(I) sulfide tend to oxidize into silver sulphate. Silver(I) oxide or silver nitrate is the raw material.

CAS No.:21548-73-2 EC No.:244-438-2 Molecular Formula:Ag2S Molecular Weight:247.80
Density:7.234 Melting Point:825℃

Silver sulfide uses as analytical reagent. It is raw material for alloys and ceramics too.

Zirconium Powder 99%

Zirconium metal is available in form of powders, chunks, ingots, lumps, pieces, sheets, foils, particles, slugs, cylinders, rods, cubes and targets. It is light gray metal or gray amorphous powder, which is insoluble in water, but soluble in hot concentrated acid, hydrofluoric acid, aqua regia and concentrated sulfuric acid. It is known as sponge zirconium. Zirconium metal is relatively stable in air, however zirconium powder is easy to ignite in air at high temperature and turns out zirconium dioxide. Zirconia is raw material for ceramics, grinding granules,  zirconium oxide ZrO2 fiber, plastic and rubber. Zirkonium powder is with purity 99% normally. The purity of sponge Zr powder is 99.4%. However the purity of zirconium lump reach 99.9%. Fine zirconium wires can be ignited by match. At high temperature, it can compound with oxygen, nitrogen and hydrogen.

Zirconium is attractive to oxygen, which could take away oxygen from magnesium oxide, beryllium oxide and thorium oxide and form ZrO2 itself. It owns strong hydrogen absorption property. The maximum hydrogen absorption capacity is equal to ZrH1.93, which can be raw material hydrogen storage material. If the hydrogen absorption capacity is higher than the hydrogen content of ZrH,  the brittleness of zirconium increase, which is easy to process powder. Zirconium owns good corrosion  resistance to diluted hydrochloric acid and dilute sulphuric acid. Its corrosion resistance is better than tantalum metal when mix with 50% NaOH soluation. So it gets great prospect in chemical industry. With 2% Hafnium in zirconium, it wouldn’t affect the corrosion resistance, however it should separate Hf when Zr act as clad material of nuclear reactor material parts.

CAS No.:7440-67-7 EINECS No.:231-176-9 Molecular Formula:Zr Molecular Weight:91.224
Melting Point:1852℃ Boiling Point:3577℃ Ignition Temperature:>200℃ Density:6.51

Zirconium powder is for preparation of nuclear industry, corrosion resistance alloy, flashlight and fireworks. It also apply to deoxidizing agent for metallurgy and chemical reagents.

The standard size of zirconium slugs are 1.2*3.5mm, 2*3mm and 1.5mm*3mm. The thick of zirconium foils are 0.2mm and 0.3mm usually. However other sizes could be customizable. Both two products are for vacuum coating, which are sputtering targets.

Zirconium alloy (ZrTh, ZrMg) is light and high-temperature resistance, which could be raw material for aircraft.
