Foundry Mullite Sand Precision Refractory Sand 30/60 Mesh For Metallurgy/Petroleum Industry

1. Mullite Sand Introduction

Mullite is a kind of aluminosilicate refractory material. It is made of hard clay mineral resources by high-temperature roasting, crushing, screening, Raymond, iron removal and other machining processes.

It has high aluminum content, low iron content, small coefficient of thermal expansion, high refractoriness, stable thermochemical properties and other excellent mullite series sands and powders.
