【摘要】 通过改变试验条件 ,用真空碳热还原煅白得到了生长良好的金属镁的晶体 ,认为要得到理想的试验结果 ,必须使反应温度高于 1 5 0 0℃、冷凝温度在镁的熔点附近 ,减小冷凝的温度梯度 ,反应过程中炉内压力变化能反映反应的进行情况 ,物料要先进行焦结更多还原

【Abstract】 Magnesium crystal can be produced successfully by changing experiment conditions by way of using vacuum carbothermic reduction of calcined dolomite.It is the opinion of the authors that the ideal test result would be obtained if reaction temperature must be over 1 500℃,condensing temperature about melting point,reducing gradient of condensing temperature,and previously coking required for raw material(Change of pressure in the vessel can reflect the reaction conditions).更多还原
