Our company holds immense experience in this domain and is involved in offering a wide range of Ammonium Chloride.

Other information:

Ammonium chloride is used as a flux in preparing metals to be tin coated, galvanized or soldered. Is used in a ~5% aqueous solution to work on oil wells with clay swelling problems. It is also used as electrolyte in zinc-carbon batteries. Other uses include in the glue that bonds plywood, cleaning products, in dyeing, tanning, textile printing and cotton clustering.

Silver Acetate

Silver Acetate is a photosensitive, white crystalline substance. It is prepared by reaction of acetic acid and silver carbonate. It can also be prepared from aqueous silver nitrate and an acetate ion. It is used in the preparation of highly reflective, conductive silvered polymer films. It also could be used to catalyze cycloaddition reactions of isocyanatoacetates. Silver Acetate containing products have been used in such products as gum, spray, and lozenges.

Silver Cyanide

Silver Cyanide is used as lining of autoclave which is used in medicine, silver plating and protective coating reagent and as additive of non-precious metals, precious metal, analytical reagent. It is also used for electrofacing of electrical contact and engine bearings of airplane. It can be used to produce Oxalonitrile.

Silver Sulfate

Silver Sulfate is an ionic compound of silver used in silver plating and as a non-staining substitute to silver nitrate.Silver sulfate is prepared by adding sulfuric acid to a solution of silver nitrate.

Palladium(II) Acetate

Palladium(II) acetate is a chemical compound of palladium. It is considered more reactive than the analogous platinum compound. It is a catalyst for many organic reactions by combining with many common classes of organic compounds such as alkenes, dienes, and alkyl, aryl, and vinyl halides to form reactive adducts. It is used to produce other palladium(II) compounds.

Hafnium Metal Industrial Grade 99.9%

Hafnium metal is a kind of transition metal of silver gray metallic, which is in powder, rod, ingot, bar, target and piece. It exists accompany with zirconium normally. There are two crystal structures of hafnium, one is hexagonal close packing (α-type at less than 1300℃, the other is body-centered cubic (β-type). Hafnium rod is ductile metal, however it turn hard and brittle when impurities exist. It is stable in air and turn dark when igniting. Hafnium wire can ignite by match. Its property is close to zirconium. It is soluble in  aqua regia and hydrofluoric acid, but doesn’t dissolve in water, dilute acid or alkali. Hafnium alloy (Ta4HfC5) is the material of highest melting point that is about 4215℃ at present.

Hafnium Metal

Applications

Hafnium metal powder can be as cathode of X-ray tube. Hafnium alloys with tungsten or molybdenum can be as electrode of high voltage discharge tube. Hf-Ta alloy is raw material for chisel tool steel and resistance material.

Hafnium powder can be thruster of rocket. it is a kind of additive for hydraulic oil, which prevent the volatilization when high-risk operations. It has strong resistance to volatile. It works in industrial hydraulic oil and medical hydraulic oil.
