Our Antimony Compounds
Five specialty antimony products — manufactured and traded to exacting standards for over 35 years. Each product is batch-tested for purity, consistency, and compliance before dispatch.
Antimony Trioxide
Antimony Trioxide is the most important commercial compound of antimony. Paras Oxide manufactures it in two precision grades — Fibre Grade for flame retardant applications in textiles and polymers, and Catalyst Grade for use in PET resin production.
Key Applications
- Flame retardant synergist in textiles, carpets & upholstery
- Flame retardant additive in plastics, rubber & coatings
- Catalyst in PET (polyethylene terephthalate) production
- Pigment and opacifier in glass & ceramics
- Stabilizer in PVC compounds
Antimony Trichloride
Antimony Trichloride is a colourless, hygroscopic crystalline solid used as a key intermediate in the synthesis of other antimony compounds and as a catalyst and mordant in various industrial processes.
Key Applications
- Intermediate in synthesis of other antimony compounds
- Mordant in textile dyeing and printing
- Catalyst in organic synthesis reactions
- Analytical reagent for alkaloid detection
- Flame retardant intermediate
Potassium Pyroantimonate
Potassium Pyroantimonate is a white crystalline powder used as an opacifier in glass and ceramics, and as an analytical reagent for the detection of sodium ions. It is a specialty compound with limited global manufacturers.
Key Applications
- Opacifier and fining agent in glass manufacturing
- Opacifier in ceramic glazes and enamels
- Analytical reagent for sodium ion detection
- Specialty chemical intermediate
- Flame retardant formulations
Antimony Trisulphide
Antimony Trisulphide (also known as Antimony Sulphide or Stibnite) is an orange-red to black powder used in pigments, pyrotechnics, rubber vulcanization, and as a friction material component.
Key Applications
- Pigments and colorants (orange-red shades)
- Pyrotechnic compositions and safety matches
- Rubber vulcanization accelerator
- Friction material component in brake linings
- Semiconductor and photovoltaic research
Antimony Metal Ingot
Antimony Metal Ingot is a silvery-white, brittle metalloid traded in ingot form. Paras Oxide sources and supplies high-purity antimony metal ingots suitable for alloying, flame retardant compound production, and semiconductor applications. Available in standard purity grades to meet diverse industrial requirements.
Key Applications
- Lead-acid battery alloy hardener (lead-antimony alloy)
- Raw material for antimony compound manufacturing
- Flame retardant intermediate production
- Bearing metals and type metal alloys
- Semiconductor and thermoelectric applications
