摘　　要：论述了具有中国自主知识产权的碳碱法生产硼砂工艺的诞生及演变、完善、发展的过程。碳碱法工艺由于具有许多优越性,已成为中国制造硼砂的唯一方法,在经历小试、中试到实现工业化的历程中及由常用的硼镁矿资源到后备资源——硼铁矿采用这条工艺的加工过程中,均显示出了强大的生命力。讨论了强化碳碱法工艺的途径,如用浓二氧化碳气体碳解,采用添加剂的方法,改进和放大碳解釜的结构等技术措施。The birth,evolution,improvement,and development of borax production technology with C02-soda process in possession of China＇s own proprietary intellectual property rights were discussed.Due to many advantages, CO2-soda process had become the only way to produce borax in China.It had showed its strong vital force both in the course of bench-scale test, pilot-scale test,and industrialization,and in the processing of back-up paigeite resource from common szaibelyite resource. The ways,such as concentrated CO2-soda r^action,additive adoption and carbon dioxide-soda reactor improvement and magnification etc., that could strengthen CO2-soda process were demonstrated.
