Natural Bauxite Mullite Bricks Material Good Thermal Shock Resistance

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

 1. Natural Sintered Mullite Introduction

 
Natural Sintered Mullite is made from the natural high-quality Bauxite, be processed through multi-level homogenization and calcined over 1750degree. It is of high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and excellent chemical-resistance. It is ideal raw material for refractory products such as different shaped and unshaped refractory materials, advanced ceramic sanitary ware body, precision casting models and so on.
