Magnesia Alumina Carbon Brick Introduction
Magnesia alumina carbon brick is a kind of refractory bricks that are made of special-grade high-alumina bauxite or emery, magnesia, and flaky graphite as the main material. Magnesia alumina carbon brick has the characteristics of high corrosion resistance, high refractoriness, and good mechanical behavior under high temperature, etc.
In order to improve the magnesia carbon bricks oxidization can appropriately add some Si powder, Al powder, SiC powder or silica iron powder, and other additives, with resin as the binding agent, high-pressure forming, after treatment of 200～300℃, it can be used without calcination.
Magnesia Alumina Carbon Brick Properties
- High refractoriness
- High corrosion resistance
- Good mechanical behavior under high temperature
- Good performance in thermal resistance
