一、前言硼及其化合物在现代无机盐工业中,具有极其重要的地位和意义。它广泛应用于国防、化工、电子、冶金、医药各工业部门,以及近代尖端科学技术领域。国外硼资源主要分布于美国、土耳其和苏联等国,其储量占世界储量的90%以上。苏联化学加工的硼矿石品位在20—25%B_2O_3以上,美国、土耳其化学加工的硼矿石品位高达40—45% First, the preface Boron and its compounds in the modern inorganic salt industry, has an extremely important position and significance. It is widely used in national defense, chemical, electronics, metallurgy, medicine and other industrial sectors, as well as modern cutting-edge science and technology. Foreign boron resources are mainly distributed in the United States, Turkey and the Soviet Union and other countries, whose reserves account for more than 90% of the world’s reserves. The grade of boron ore chemically processed by the Soviet Union is above 20-25% B_2O_3, the grade of boron ore chemically processed in the United States and Turkey is as high as 40-45%
