A classical method used to remove bubbles during glass melting is to introduce ''fining'' agents such as arsenic, antimony oxides or sulfate in small quantities [4]. The efficient melting factors defined in are temperature ensuring[7]. ...
The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide. Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide …

Fig. 11 and Table 4 show that crude antimony with an average purity of 96.15 wt% was obtained. 92.6% of the initial antimony was enriched and recovered as crude antimony by one step conversion. Antimony volatilization rate was low because of the low treatment temperature and a fast conversion and reduction of volatile Sb 2 S 3 and Sb 2 O x (x …
ANTIMONY SULFIDE presents a serious fire risk if exposed to oxidizing agents. Crystals burn with a blue flame when heated in air [Mellor 9:522 1946-47]. Emits toxic antimony and sulfur oxide fumes if heated to high temperatures.
Antimony trisulfide (Sb2S3) is found in nature as the crystalline mineral stibnite and the amorphous red mineral metastibnite.[3] It is manufactured for use in safety matches, military ammunition, explosives and fireworks. It also is used in the production of ruby-colored glass and in plastics as a flame retardant.[4] Historically the stibnite ...
Antimony sulfate, Sb2(SO4)3, is a hygroscopic material formed by reacting antimony or its compounds with hot sulfuric acid. It is used in doping of semiconductors and in the production of explosives and fireworks.[1]
