Antimony Oxide MicroPowder  Products Features:

Antimony oxide is a white powder and derives from the mineral stibnite (antimony sulfide) or is produced by oxidation of antimony metal or as a by-product from refineries or lead and antimony alloys. Sometimes it acts like metal and sometimes like a non-metal.

In the glass industry, small percentages of antimony oxide are used to eliminate optical glass bubbles, to bleach special glasses and as a stabilizing agent in the production of emerald green glass. It is slightly fluxing in high-temperature glazes.

Antimony oxide is used as an opacifier in porcelain enamel (lead mainly but has been partially replaced by titania) and ceramic glazes. However, it can give a yellowish color if the enamel contains lead, due to the precipitation of yellow lead antimonate (known as Naples yellow).

Antimony is also used as a yellow body stain in combination with rutile or titanium.

The brick industry uses antimony to discolor the surface of red clay and obtain a soft color to produce a varied color.

It is valuable for its high “color” (covering power or opacity) when used together with halogen-containing compounds. Antimony nanophase oxide is also available in Beijing Sunpu, has a very high surface catalytic activity can be used as an accelerator in the polyester industry Terylen and in high-quality plastic, rubber, dye, insulating fiber materials, chemical compound materials, etc.
