What is the refractory density of magnesia?

The refractory density of magnesia can vary depending on the specific type of magnesia being used and its properties, as well as factors such as porosity and manufacturing methods.

Generally speaking, the refractory density of magnesia ranges from 2.9 g/cm3 to 3.2 g/cm3, which is relatively high compared to other refractory materials. Magnesia has a high density due to its high melting point and strong chemical bonds, which make it resistant to wear, corrosion, and thermal shock.

However, the actual density of magnesia used in refractory applications can vary based on the specific grade or type of magnesia being used, as well as the manufacturing process and any additives or binders that may be used. It is important to consult with manufacturers or suppliers of magnesia to determine the appropriate density for a specific application.
