Product Name:Brucite (Natural Magnesium Hydroxide)
English Name:Brucite (Natural Magnesium Hydroxide)
CAS No.:1317-43-7
Aliases:Magnesium hydroxide mineral, Magnesium hydrate
Molecular Formula:Mg(OH)2
Physical Properties:White to gray-white powder or crystal, molecular weight 58.3, density 2.3-2.6 g/cm³, Mohs hardness 2-3, refractive index 1.56-1.58, pH value (aqueous suspension) 9-10, decomposition temperature about 340°C, loss on ignition 28-30%, volume resistivity 10^8-10^10 Ω·cm.
Uses:Used as a halogen-free flame retardant in rubber, plastics and cables; used to manufacture asbestos-free thermal insulation materials, refractory materials and protective layers for nuclear reactor containment in nuclear power plants; serves as a neutralizer, adsorbent for acidic wastewater and an agent for flue gas desulfurization; also used as papermaking filler, welding electrode coating, and in production of light-burned and dead-burned magnesia.
