Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in the United States that produce antimony ...

Gallo et al. (2013) tailored the flame retardant property of kenaf fibers reinforced PHBV/PBAT (30/70, w/ww) composites by preparing multicomponent laminates, shown in Fig. 19.10(a) Results showed that the introduction of fibers and flame retardants composed of aluminum diethyphosphinate (AlPi) and antimony oxide (Sb 2 O 3) only slightly prolonged the time to ignition, as shown in Fig. 19.10(b).

CN103866121A - Method for preparing sodium

The invention discloses a method for preparing sodium antimonate from an antimony oxide ore via an alkaline approach. The method comprises the following steps: (1) leaching the antimony oxide ore, (2) purifying filtrate, and (3) oxidizing the purified filtrate. The method is high in recovery rate, the leaching rate of antimony is 95-99%, the direct recovery rate of sodium antimonate is 90-95% ...
