A method for preparing beryllium fluoride and a method for preparing ultra-high purity metal beryllium

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 beryllium metal. Background technique [0002] Beryllium is a material with special properties, and some of its properties, especially nuclear and physical properties, cannot be replaced by any other metal materials. The density of beryllium is low, the specific elastic modulus is at least 6 times that of any other metal, light weight, high rigidity, good thermal performance, high melting point, high specific heat, high thermal conductivity and suitable thermal expansion rate, etc. Excellent performance, sound transmission faster than any other metal. Therefore, the application scope of beryllium is mainly concentrated in nuclear industry, weapon system, aerospace industry, X-ray instrument, electronic information system, automobile industry, household appliances and other fields. ...
