前言日本从1950年左右开始使用锆,战争年代是利用稀土残渣回收锆,经化学处理制成脂肪酸锆。最初是作为纤维防水剂用,从60年代开始将锆英石进行粉碎和电溶得到的产品用于陶瓷及耐火行业,用湿法生产的氧化锆则用于电子材料、光学玻璃及化学产品材料。生产原子能用的金属锆现已逐步实现工业化生产。氧化锆的最新用途是化学合成陶瓷材料。在日本工业中使用氧化锆已有30多年的历史,目前氧化锆的年需要量为6400～6500吨。在氧化锆利用方面非常值得重视的新动向是许多生产厂家对精细陶瓷这个应用领域抱着极大的希望,虽然该行业目前的年需要量不超过100吨,但已出现十多家新的生产厂
Preface Japan began to use zirconium from about 1950, and the era of war was the recovery of zirconium from rare earth residues and the chemical treatment of zirconium fatty acid. Originally used as a fiber waterproofing agent, products obtained by crushing and electrifying zircon from the 1960’s are used in ceramics and refractory industries. Zirconia produced by wet processes is used in electronic materials, optical glass, and chemical product materials . The metal zirconium used for the production of atomic energy has been gradually industrialized. The latest use of zirconia is the chemical synthesis of ceramic materials. Zirconia has been used in Japanese industry for more than 30 years. At present, the annual requirement of zirconia is 6,400 to 6,500 tons. The new trend that deserves attention in the utilization of zirconia is that many manufacturers hold great hopes for the application of fine ceramics. Although the current annual requirement for the industry does not exceed 100 tons, more than a dozen new products have emerged plant
