刚才落了一段 麻烦在把这段翻译下 谢谢 caustic calcined magnesia is produced by calcining magnesite in furnaces,typically at temperatures of 800~900℃.global production is estimated at around 1.6~1.7 Mt/a, of which chian accounts for 35%~40%.It has a variety of agricultural, environmental, chemical and industrial applications and is also the precursor for refractory magnesias.
