Preparation and application of antimony sulfide Sb2S3 powder

Overview of antimony sulfide

Sulfides are crystals or powders ranging from bismuth to dark gray. The template is oxidized in the open air. It is also soluble in involatile hydroxide solution, soluble in concentrated hydrochloric acid, and releases water-insoluble hydrogen sulfide. Pure tri-is sulfide is a yellowish amorphous powder, insoluble in water, acetic acid and acetic acid, but soluble in concentrated hydrochloric acid, ethanol, and ammonium sulfide solution. The biphenyl sulphur in fireworks is processed into hydrazine powder, which is black or gray-black powder with metallic luster, insoluble in water, and strong reducibility. poisonous.

The tri-oxidant is stable at room temperature, but the corresponding oxide can be obtained in the air, and can also be reduced by H2 or Fe.

Bismuth trioxide is bismuth dissolved in concentrated hydrochloric acid.

Antimony sulfide Preparation

There are three preparation methods: natural mineral processing method, antimony white conversion method and direct chemical method.

Natural ore processing method

Antimony sulfide products are obtained from natural antimony ore after screening, crushing and other processing.

Antimony White Conversion Method

Reaction equation

Sb2O3+4Na2S+Ca(OH)2+3H2O→Sb2S3+8NaOH+CaS

Operation method: After mixing Sb2O3 1.80kg, Ca(OH)2 0.6kg and H2O 6kg, heat at 80℃ for 1h. Dissolve 2.41kg of 60% Na2S in 3L of water to make a Na2S solution, add this Na2S solution to the above mixture within 30 minutes at 80°C under stirring, and maintain stirring for another 30 minutes. Then it was acidified with 30% HCl within 3 hours to a pH of 0.4. The temperature was raised to 95°C, and then stirred for 3 hours, cooled, filtered, washed, and dried to obtain Sb2S3 pigment.

Direct legalization

Reaction equation

3S+2Sb→Sb2S3

Operation method: After the metal antimony is melted at high temperature, sulfur vapor is introduced into it to directly combine to produce antimony trisulfide. The amount of sulfur is 103%-115% of the stoichiometric amount, the reaction is stirred for 0.3-1h, and the reaction temperature is maintained at 650-850°C.

Application of antimony sulfide

Antimony sulfide is mainly used to make matches and fireworks, various antimony salts and colored glasses. The rubber industry is used as a vulcanizer and military workers. It can also be used as a photoelectric material, and has good application prospects in the field of solar cells and photochemistry. Make fireworks, glass, explosives, paints.
