Products Overview
Our Silicon mullite brick is a high-performance refractory product engineered for cement kiln transition zone, cooling zone, and kiln mouth service. The product family is made from high-grade bauxite clinker and high-quality silicon carbide as the main raw materials and firing at high temperature. The product has high cold compressive strength and high structural strength in high temperature, good thermal shock resistance, and forms a protective layer during using. It has good wear resistance and good anti-flaking property, applied for transition zone, cooling zone, kiln mouth of cement kiln and other parts.
The Silicon mullite brick product family is offered in three engineering-proven GMZ chemistry grades. The CH-GMZ65 grade features Al2O3 content maximum 65% and Refractoriness minimum 1790 °C for general cement kiln transition zone service, with Bulk Density minimum 2.50 g/cm3, Apparent Porosity maximum 20%, Cold Crushing Strength minimum 80 MPa, High Temperature Modulus of Rupture minimum 8 MPa at 1450 °C, Refractoriness Under Load minimum 1550 °C at 0.2 MPa, Thermal Shock Resistance minimum 10 cycles at 1100 °C. The CH-GMZ63 grade features Al2O3 content maximum 63% for higher-demand cement kiln cooling zone service, with Bulk Density minimum 2.55 g/cm3, Cold Crushing Strength minimum 90 MPa, High Temperature Modulus of Rupture minimum 12 MPa, Refractoriness Under Load minimum 1650 °C, Thermal Shock Resistance minimum 12 cycles, and Wearing coefficient 8.2. The CH-GMZ60 grade features Al2O3 content maximum 60% for highest-demand cement kiln service, with Bulk Density minimum 2.60 g/cm3, Apparent Porosity maximum 21%, Cold Crushing Strength minimum 95 MPa, High Temperature Modulus of Rupture minimum 15 MPa, Refractoriness Under Load minimum 1680 °C, Thermal Shock Resistance minimum 15 cycles, and Wearing coefficient 8.5.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Silicon mullite brick grade is engineered to ASTM, GB/T, and ISO refractory standards.
