Corundum mullite bricks are widely used in the fields of high-temperature sintering of zirconia ceramics, fluorescent materials, electronic ceramics, magnetic materials and ceramic powders due to the combination of the strength of corundum and the thermal shock resistance of mullite. The following Sunrise refractory materials simply tell you what the characteristics of the corundum mullite bricks are.
First of all, Sunrise Group tells everyone about the production process of the corundum mullite:
Corundum mullite bricks are usually made of synthetic mullite. The mullite granules can be used as aggregates. A-AI2O3 powder is used as powder, and fused or sintered corundum granules can be used as aggregates. Stone powder is a powder.
The aggregate and the powder are compounded according to a certain ratio and particle size gradation, and the sulfite pulp waste liquid is used as a binder, and the materials are fed in a certain order. Fully knead evenly and form with a friction brick press or a hydraulic press. After the bricks are dried, they are fired at 1650 ~ 1750C.
Then, Sunrise Group further introduced the characteristics of the corundum mullite brick:
(1) High temperature resistance, high refractory temperature, high load softening temperature.
(2) It is resistant to chemical attack and has strong resistance to acidic solutions or slag.
(3) Antioxidant. It is not easy to chemically react with gases such as O2, H2, and CO.
(4) It has good thermal stability, high temperature and volume stability, and is not easy to expand or shrink.
(5) It has good thermal shock resistance and is resistant to rapid cooling and rapid heat.
(6) The room temperature has high compressive strength and is not easily worn during handling or unloading.
(7) Heavy materials have good compactness, high compressive strength, resistance to various corrosive bodies, and thermal shock stability.
Good, excellent thermal conductivity and wear resistance.
(8) Lightweight material has uniform internal structure, high compressive strength, corrosion resistance, thermal shock resistance, anti-oxidation, and use
High temperature and low thermal conductivity. zhengzhou Sunrise Industrial refractory brick manufacturers are available from stock, the price is more suitable.
