The production of high-purity antimony xide (Sb 2 O 3) in this study involves the removal of arsenic (As) from Sb 2 O 3 using the sulfurization precipitation method. This method is pivotal in reducing the As content to as low as 0.1 ppm, showcasing its efficiency and potential for broader industrial applications.
Antimony xide itself has no flame retardant function, however, when it is used together with halogenated compounds, the synergistic effect of the mixture creates the flame retardant properties. Antimony xide reacts with halogenated compound and creates the chemical compounds, which generate the flame retardant function, through the ...
Antimony xide is made by roasting antimony metal in a furnace with oxygen present. The antimony vapors react with the oxygen and form a fine, white dust that is collected …
A process for the production of antimony xide comprising the steps of: (i) reacting antimony trisulfide with iron (III) chloride to produce antimony trichloride; and (ii) hydrolyzing antimony trichloride to produce antimony xide. In a preferred embodiment, the process is substantially closed or near-closed loop. Antimony xide is a known …
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …
Most commercial grades of antimony xide contain between 99.2% and 99.5% antimony xide with varying amounts of impurities such as arsenic, iron and lead. Com-mercial suppliers offer various grades of antimony xide based on the relative tinting strength of their product, which is a func-tion of particle size. Antimony xide also ...
