summary

Corundum Mullite Plate and Corundum Mullite Support

Overview

Corundum mullite is a composite ceramic material combining the strengths of corundum (aluminum oxide, Al₂O₃) and mullite (alumino-silicate, 3Al₂O₃·2SiO₂). This synergy produces a material with outstanding mechanical strength, thermal stability, corrosion resistance, and thermal shock resistance, making it a preferred choice in high-temperature and high-stress industrial applications.

What is a Corundum Mullite Plate?

Corundum mullite plates are refractory ceramic plates, most often used as kiln furniture or structural supports in high-temperature furnaces. They are engineered to withstand repeated thermal cycling and mechanical loads while providing a stable base for other materials during firing and sintering.

Key Properties

High-temperature stability: Maintains integrity above 1700℃.

Excellent thermal shock resistance: Resilient to rapid temperature changes.

High compressive and flexural strength: Supports heavy loads without deformation or cracking.

Low porosity and high density: Minimizes corrosive penetration and increases lifespan.

Superior chemical inertness: Resists attack from acids, alkalis, and molten slags.

Typical Applications

Application	Benefits
Kiln set plates	High load strength, repeatable use
Furnace linings	Superior thermal and corrosion resistance
Push/Setter plates	Stability and durability under frequent cycling
Glass and ceramic manufacturing	Ensures product purity, reduces defects

What is a Corundum Mullite Support?

Corundum mullite supports refer broadly to any structural or load-bearing ceramic element made from this composite, such as beams, stands, posts, and catalyst carriers. Their principal role is to support components or workpieces in high-temperature reactors, kilns, or other thermal processing equipment8 9 2.

Principal Uses

Support for sintering and firing: Safely bear the weight and maintain spacing of ceramic bodies, glost, or biscuit ware.

Catalyst support in petrochemical reactors: Chemically inert and heat resistant for stable operation8.

Kiln furniture: Stands, beams, and brackets optimize furnace efficiency and stacking height without warping.
