Zircon Flour
ZrSiO₄
Ultra-fine milled zircon flour supplied for ceramic glaze opacification, refractory coatings, and investment casting applications.
Overview
Zircon flour is zirconium silicate milled to ultra-fine particle sizes (typically D50 < 5 µm), providing superior opacity, surface coverage, and chemical stability in ceramic glaze and refractory coating systems. Its fine particle size enables smooth glaze surfaces and high-efficiency opacification compared to standard zirconium silicate grades.
