Antimony Trioxide 99.5%
Sinobio
28258000
Name:Antimony trioxide
CAS: 1309-64-4
Chemical formula: O3Sb2
Appearance: Ccrystal powder
Antimony trioxide (Sb2O3, Mr291.50) is a dual-type substance including cubic crystal and monoclinic crystal type. For different crystal form, the density and refractive index also slightly differ. The density and refractive index of cubic crystal is 5.2 and 2.087, respectively while is 5.67 and 2.18 for the monoclinic crystal, respectively. The Sb2O3 commonly derived from hydrolysis of SbCl3 is rhombic crystal can burn to red heat in an inert gas or in vacuum and can generate square crystal upon sublimation.
| Sb2O3 | ≥99.5% |
| As2O3 | ≤0.08% |
| PbO | ≤0 08% |
| Fe2O3 | ≤0.005% |
| CuO | ≤0.005% |
| Se | ≤0.002% |
Antimony Trioxide is widely used as a flame retardant in PVC, PP, PE, PS, ABS, PU and other plastics, with high flame retardant efficiency and little impact on the mechanical properties of the substrate (such as: fireproof uniforms and gloves, flame-retardant electronic equipment shells, flame-retardant compartments, flame-retardant wires and cables, etc.).
1. Used as filler and flame retardant in rubber industry
2. Used as enamel covering agent in enamel and ceramic products
3. Non-magnetic ceramics used in the electronics industry for the production of pressure-sensitive ceramics and magnetic head parts
4. As a white pigment and flame retardant for paint in the coating industry
5. Used as a catalyst for organic synthesis
25kg bag, 1,000kg jumbo bag/pallet, other packing will be available by customer's requests.
