General pyrochemical processes used industrially for the preparation of antimony trioxide
from sulphide ores involve roasting of the high grade ore or concentrate.
However, it should be emphasized that the lowest toxicity among all introduced samples ([W.sub.LC50SM] = 139.6 g/[m.sup.3]) was observed in PES containing 14 wt% of antimony trioxide
Unit Shipment and Revenue Forecast Discussion - Antimony Trioxide
Three different types of plasticized PVC compositions were investigated: clay filled with 52 phr plasticizer (and containing antimony trioxide
as flame-retardant synergist); clay filled with 50 phr plasticizer (without antimony trioxide
); and unfilled with 83 phr plasticizer (i.e., did not contain clay nor antimony trioxide
The admixture of inorganic fire protection agents and, namely, antimony trioxide
and molybdenum trioxide and melamine to epoxy flooring composites reduces [HRR.sub.max] and [HRR.sub.av] values, as compared to the unmodified epoxy material.
is used as a catalyst in the manufacture of PET.

In respect of processed products, Southern Africa is also a significant producer of antimony trioxide
, low-manganese iron, manganese dioxide, titanium slag, zinc metal and phosphoric acid.
Hot commissioning commences later this month leading to the production of antimony trioxide
followed by the production of antimony and gold ingot later this summer', Tri Star Resources said in statement posted on its website.
One of the materials they will produce is antimony trioxide
, which is currently used as a flame retardant in a wide range of products, ranging from textiles and furniture to plastic covers designed to reduce the risks caused by car and aircraft engine fires.
Products include Cellcom FR/ATH (aluminum tri-hydrate), Cellcom FR/ATO (antimony trioxide
), Cellcom FR/DBPE (decabromo diphenylethane), Cellcom FR/DPBO (decabromo diphenyloxide), Cellcom FR/MHO (magnesium hydroxide), Cellcom FR/HBCD (hexabromocyclododecane) and Cellcom FC/ MC (melamine cyanurate).
