摘要
利用不溶性含钾岩石和石灰石为主要原料,适量添加硫酸钠作为反应助剂,经高温煅烧制备出钾钙肥。对助剂硫酸钠的加入量、烧结温度、烧结时间进行了研究,得到了烧制钾钙肥的优化条件。
Utilizing the undissolved potassium containing rock and limestone as the main raw material. Adding sodium sulfate as a reaction agent, potassium calcium fertilizer was prepared by high temperaturecalcination. The additive sodium sulfate addition, sintering temperature, sintering time was studied. The optimal conditions were obtained.
