Detailed introduction

Generally, it can be divided into sintered magnesia brick (also known as fired magnesia brick) and chemically bonded magnesia brick (also known as unburned magnesia brick). Magnesium bricks with high purity and firing temperature are called direct bonded magnesia bricks because of the direct contact of periclase grains. The bricks made from electrofused magnesia sand are called electrofused re-bonded magnesia bricks.

Magnesium bricks have high refractoriness, good alkaline slag resistance, high load softening temperature, but poor thermal shock resistance. Sintered magnesia bricks are made from brick-making magnesia bricks. After crushing, proportioning, mixing and moulding, they are fired at high temperatures of 1550-1600 and high purity products are fired at temperatures above 1750. Non-cast magnesia brick is made by mixing, shaping and drying magnesia with appropriate chemical binder.
