タイトルまたは説明

High purity magnesium oxide is white amorphous powder with good light permeability, odorless, tasteless, and non-toxic. High purity magnesium oxide has the characteristics like excellent alkali resistance and electrical insulating in high temperatures, high thermal expansion coefficient and thermal conductivity. The volume density is 3.*8g/cm3 at *5℃. Melting point is ***2 ℃, boiling point is ***0 ℃. It is insoluble in water and ethanol, soluble in acid and ammonium salt. High purity magnesium oxide transforms into crystals after burning in high temperature above ***0 ℃, transforms into dead burned magnesium oxide or sintered magnesium oxide. Absorbing carbon dioxide in the air, high purity magnesium oxide transform into basic magnesium carbonate.
