Substrate compounds with iron acid magnesium, magnesium aluminum , forsterite, calcium and magnesium olivine and other minerals. Due to the magnesite brick is alkaline magnesium oxide content, density, less water, forming high pressure, low porosity, volume density, etc.
So as long as it is composed of many mineral substances of magnesia brick. Magnesite brick with strong alkali, high density, etc.
