Abstract

The invention relates to a preparation method of beryllium fluoride and a preparation mode of ultrahigh-purity metal beryllium. The beryllium fluoride is prepared by mixing and heating beryllium hydroxide and hydrofluoric acid with the following steps: pouring the beryllium hydroxide and the hydrofluoric acid into a reactor, and sealing; energizing, stirring, and powering on for heating; putting aprepared beryllium fluoride material into a drying box for drying, so as to obtain beryllium fluoride crystal grains; pouring into a stainless steel pulverizer, and pulverizing, so as to obtain beryllium fluoride powder, and storing; preparing the beryllium fluoride powder into coarse beryllium powder, purifying, and smelting into a beryllium ingot. The preparation method of the beryllium fluoride and the preparation mode of ultrahigh-purity metal beryllium have the advantages that the technology is simple, and introduced impurities are fewer; compared with the traditional technology, the production efficiency is higher; the purity of the obtained product is high, energy is saved, the treatment cost is low, and the purity of the prepared beryllium is high.

Description

technical field [0001] The invention relates to the field of metal beryllium purification, in particular to a method for preparing beryllium fluoride and a method for preparing ultra-high-purity metal beryllium. Background technique [0002] Beryllium is a material with special properties, some of its properties, especially nuclear properties and physical properties, cannot be replaced by any other metal materials. Beryllium has a low density, a specific elastic modulus at least 6 times that of any other metal, light weight, high stiffness, good thermal properties, and has excellent properties such as high melting point, high specific heat, high thermal conductivity and suitable thermal expansion rate, sound transmission. faster than other metals. Therefore, the application range of beryllium is mainly concentrated in the nuclear industry, weapon systems, aerospace industry, X-ray instruments, electronic information systems, automotive industry, household appliances and oth...
