Zircon Glaze Opacifier is a high‑purity zirconium silicate powder supplied by Buntrock International Pvt. Ltd. It is composed of ZrSiO4 and displays a melting point greater than 4000 °F, a Mohs hardness of 7.5, a coefficient of thermal expansion of 4.2 × 10⁻⁶ cm/cm/°C and an index of refraction of 2.0. The material also exhibits a thermal conductivity of 14.5 BTU/sq ft·hr·°F·in and an average particle size reported as 1500 Å. These properties make it suitable for demanding glaze formulations where opacity and thermal stability are required.
In the ceramics market the product is offered in standard mesh grades that work for both wet and dry glaze systems. Typical purity for this class of opacifier exceeds 99.5 % and the average particle size of 1500 Å is common for fine glaze powders. Spectralux values are provided for several grades, for example the 3500 µm grade ranges from 1.90 to 2.10 µm and the 7000 µm grade from 0.95 to 1.05 µm, which are typical ranges used to control colour and translucency. The powder is supplied in 25 kg paper bags, a packaging format standard for bulk ceramic additives.
Tile manufacturers, sanitary‑ware producers and table‑ware makers are the primary buyers of this opacifier because it delivers the glossy and satin finishes demanded by end‑users. Buntrock International typically ships the product in bulk containers; exact MOQ, incoterms and payment terms should be confirmed directly with the supplier. Importers are advised to request a material safety data sheet and, where required, a certificate of analysis to verify purity before placing a large order.
