| Rubber Industry | Flame Retardant Additive | Incorporated into rubber products to improve fire resistance for applications such as cable sheaths and conveyor belts requiring high flame retardancy |
| Textile Industry | Textile Flame Retardant Treatment | Applied in conjunction with other flame retardant components during textile impregnation or coating processes to enhance fire resistance |
| Coatings Industry | Flame Retardant Additive for Coatings | Incorporated into intumescent coating formulations to improve char formation and thermal insulation performance at elevated temperatures |
| Electronics & Electrical | Flame Retardancy for Electronic Encapsulation Materials | Used in plastic components such as printed circuit boards and electrical enclosures to achieve higher UL94 flame retardancy ratings |
| Glass & Ceramics Industry | Clarifying Agent | Acts as a clarifying agent in glass manufacturing to facilitate removal of bubbles from molten glass |
| Metallurgical Industry | Raw Material for Antimony Alloy Production | Serves as a precursor in the production of antimony-based alloys for battery grids and bearing alloys |
| Chemical Production | Catalyst Support or Intermediate | Employed as a catalyst or catalyst support in certain oxidation reactions, including auxiliary catalysis in specific polymerization processes |
Manufacturing Quality Control of Antimony(III) Oxide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Antimony Trioxide Content | Gravimetric Analysis | Precipitation of antimony as Sb2O3 after controlled decomposition and ignition; mass loss/gain calculation. |
| Assay (Sb2O3 %) | Acid-Base Titration | Dissolution in HCl followed by complexometric titration with EDTA using xylenol orange indicator. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-OES | Multi-element quantification after acid digestion using plasma excitation and optical emission detection. |
| Iron (Fe) Impurity | AAS | Atomic absorption measurement at characteristic wavelength after sample dissolution in HCl. |
| Chloride (Cl-) | Potentiometric Titration | Titration with AgNO3 using silver electrode to detect endpoint via potential change. |
| Sulfate (SO42-) | Gravimetric Analysis | Precipitation as BaSO4 after acidification and ignition; weight determination. |
| Loss on Ignition (LOI) | Thermogravimetric Analysis | Mass loss measured upon heating to 1000 C under air to remove volatiles and hydrates. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate size distribution. |
| Bulk Density | ASTM D1895 | Measurement of mass per unit volume using standardized funnel and cup apparatus. |
| pH of Aqueous Slurry | pH Meter | Measurement of pH in a defined water suspension (e.g., 10% w/w) using calibrated pH electrode. |
| Water Soluble Matter | Gravimetric Analysis | Extraction with hot deionized water, filtration, evaporation, and residue weighing. |
| Residue on Sieve (e.g., 45 um) | Dry Sieving | Mechanical separation using standard sieve; determination of oversize fraction by mass. |
