mullite refractory brick For Glass Furnace melting pool
Product Description
Description of Zirconia mullite refractory brick
Sintered zirconium mullite brick is a special refractory material
made by using industrial alumina and zircon concentrate as raw
materials and introducing zirconium oxide into the mullite matrix
through a reactive sintering process. Introducing zirconia into
mullite bricks, and using the phase change toughening of zirconia
can greatly improve the high-temperature mechanical properties of
mullite materials. Zirconia can promote the sintering of mullite
materials. The addition of ZrO2 can accelerate the densification
and sintering process of ZTM materials due to the generation of low
melting point substances and the formation of vacancies.
Application of Zirconia mullite refractory brick
Zirconia mullite refractory brick are widely used in non-metallic
materials industry, petrochemical industry, steel smelting,
military industry, electronics industry and other fields. For
example: silicon steel heating furnace lining in metallurgical
industry, thermal insulation lining of high-temperature equipment
of hydrogen production furnace and gasifier in petroleum industry,
thermal insulation lining of cemented carbide intermediate
frequency furnace, etc.

Product Process
Manufacturing process of Zirconia mullite refractory brick
Characteristics of Zirconia mullite refractory brick:
1. Resistance to glass liquid and alkali corrosion, erosion
resistance
2. High mechanical strength, good thermal shock stability
3. Reheating shrinkage and high temperature creep are small
4. Dense crystal structure
Zirconium mullite brick application: mainly used for paving the
bottom of the glass melting part, paving the bottom of the cooling
part, small furnace, regenerator lattice body, L-shaped hanging
wall nose area, etc.
It is an indispensable key supporting material for a wide range of
applications in large float glass kilns.
It is used in large glass kiln melting pool, picture tube kiln,
regenerator partition wall brick, and chemical and metallurgical
industry kilns that are corroded by solution.
