Brief Analysis of Tianyang Refractory High Purity Magnesia Brick with High Quality and Low Price

In common magnesia bricks, the silicate phases such as forsterite and magnesite are generally used as a combination. Although the melting point of the periclase grains constituting the magnesia bricks is relatively high, it starts at about 1500 ° C.

The molten silicate phase exists, and its liquid phase has a low viscosity at high temperatures, so it reflects that the load deformation temperature and collapse temperature of ordinary magnesia bricks are not much different, but it is quite different from the fire resistance.
The starting temperature of softening of high-purity magnesia bricks can reach 1800 ℃, which is mainly because the combination of periclase grains is forsterite or dicalcium silicate, and the eutectic formed with MgO has a high melting temperature. , The strength of the character between the crystals is high, and the plastic deformation at high temperature is small, and the crystal particles are well combined. The linear expansion rate of magnesium bricks at 1000 to 1600 ° C is generally 1.0% to 2.0%, and is approximately linear. In refractory products, the thermal conductivity of magnesia bricks is second only to carbon bricks.
