What is antimony powder?
Antimony powder is used as an analytical reagent and in preparing alloys and salts to manufacture lead-antimony alloy materials, cable sheathing, and antimony compounds. Antimony powder is used as a raw material for high-purity reagents and semiconductors;
Antimony powder manufactures group Ⅲ~V compound semiconductors, high-purity alloys, and antimony sulfide.
Antimony powder is used as the dopant of silicon and germanium single crystals. Antimony is mainly used in metallurgy to make alloys; Antimony is also used in semiconductors. Antimony trioxide can also be used as a transparent enamel white pigment. Also used in printing and pigments.

Properties of antimony powder
Antimony is a glossy silver-white metal. Relative density 6.68; Melting point 630℃; Boiling point 1635℃, 1440℃ have also been reported. Soluble in hot concentrated sulfuric acid, aqua regia, insoluble in water. Flammable in case of an open fire and high heat. Powder and air can form an explosive mixture; when it reaches a certain concentration, it will explode when it meets Mars.
Preparation of antimony powder
The antimony block was added to the reactor and chlorinated with chlorine gas to obtain crude antimony trichloride. Crude antimony trichloride is placed in a still, antimony pentachloride, and other impurities are removed by vacuum distillation and then distilled at atmospheric pressure. The purity of antimony was not less than 99.999% after a reduction of 221 ~ 225℃. The purity of high-purity antimony is not less than 99. 9999% after being purified by double distillation.
Use of antimony powder
High-purity antimony prepares group Ⅲ ~ V compound semiconductors, high-purity alloys, antimony sulfide, refrigeration components and silicon, and germanium single-crystal dopants.
Safety of antimony powder
Antimony irritates mucous membranes and can cause visceral damage. It can stimulate and sensitize the skin.
Storage Condition of antimony powder Sb powder:
Store in the cool, ventilated warehouse. Keep away from fire and heat. Keep the container sealed. It should be stored in the storeroom's clean, dry, and basic acid alkali atmosphere. Products in the process of transportation should be rain and moisture-proof, not violent collision. Immediately wash with soap and water.
