High Temperature Tunnel Kiln Sintered Mullite 47% 60% 70% for Refractories Bricks

 1. Natural Sintered Mullite Introduction

Mullite is a mineral produced by aluminosilicates at high temperatures. Mullite is formed when aluminosilicates are artificially heated. Natural mullite crystals are slender, needle-like and radially clustered. Mullite as a great refractory material can be widely used in refractories, ceramics, metallurgy, casting, electronics and other industries.
