Product introduction

At high temperature it has excellent alkali resistance and electrical insulation. High coefficient of thermal expansion and thermal conductivity. It has good light transmittance. White amorphous powder. Odorless, tasteless and non-toxic. The relative density is about 3.58 (25 ℃). Melting point 2852 ℃, boiling point 3600 ℃ Insoluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution. It can be transformed into crystal after burning at a high temperature above 1000 ℃. When the temperature rises above 1500 ℃, it becomes dead burned magnesium oxide or sintered magnesium oxide. When it meets carbon dioxide in the air, will be formed basic magnesium carbonate.

Product use

It is widely used as high temperature and heat resistant material. In the field of ceramics, it is used as raw material for transparent ceramic crucible and substrate etc. In electronic materials and electrical fields, it is used for magnetic device fillers and various carriers. As a ceramic substrate, the thermal conductivity is 2 times higher than that of alumina, and the loss of electrolyte is only 1 / 10 of that of alumina. It can also be used as filler for heat-resistant coatings.
