| Abstract: | High-purity magnesium oxide was prepared by magnesium hydroxide method with brine as raw material.The brine was treated through co-precipitating and ultrafiltration processes and.effects of such factors as brine concentration,reaction temperature and feeding rate of ammonia water on purity of magnesium oxide were investigated primarily.The content of magnesium oxide in the product exceeded 99%. |
