EXTERNAL LINKS &GENERAL DESCRIPTION |
||
|
GENERAL DESCRIPTION: Magnesium oxide (also known as magnesia) is formed commercially by heating magnesite to 600-800 C, which drives off most of the CO2. It has good thermal conductivity and electrical resistivity at elevated temperatures. It is used for refractory applications, absorbent, catalyst, catalyst support, Magnetron sputtering source, animal feedstuffs, fertilizers, special cements, gas-scrubbing equipment, and a variety of magnesium chemicals. Application: Cattle feed, paper and pulp production, fertilizers, sorelcement and grinding wheels, brakelinings, water purification, slurry treatment, chemical application, sugar refining, rubber and plastic, glass and enamel and metallurgical application |
