Beryllium (Be, atomic number 4, formerly also known as glucinium) is a lightweight, dark, silver-grey metal with hexagonal-close-packed structure, with high thermal stability and conductivity, flexural rigidity. Beryllium was on the EU’s list of critical raw materials in 2011, 2014 and 2017.

2025年2月17日 · This research provides a novel approach to beryllium scrap purification, contributing significantly to the optimization of the beryllium supply chain and offering valuable insights into sustainable metal refinement practices.

The pebbles are further purified by melting them in a vacuum furnace, in which the vacuum allows any magnesium impurity to boil off to be collected and recycled, and the remaining beryllium metal is thus refined to as high as 99.99% beryllium content.

The metallic form of beryllium is obtained from the hydroxide using a magnesium reduction process, converting beryllium fluoride to beryllium pebbles and magnesium fluoride. These pebbles undergo further refinement to achieve purity …

An investigation was made of the electrorefining of beryllium in electrolytes composed of a LiCl- KCl eutectic mixture plus varying amounts of BeCl/sub 2/. Results showed a 99% or better reduction of oxygen and magnesium and a substantial reduction of other minor metallic impurities. Extremely pure beryllium metal was produced.

An electrolytic process of refining beryllium that would roduce material sufficiently pure for nuclear engineering applications was investigated. Nickel strip cathodes and commercial grade beryllium anodes were used. To avoid contamination by chlorine, an electrolyte of KF - …

2020年1月15日 · Mining and refining of beryllium in the US, which accounts for as much as 90 percent of global production, is dominated by Materion Corp. Formerly known as Brush Wellman Inc., the company operates the Spor Mountain bertrandite mine in Utah and is the world's largest producer and refiner of beryllium metal.

2023年5月28日 · The refined beryllium hydroxide can be obtained by the dissolution of beryllium hydroxide with sulfuric acid, EDTA complexation, and removal of impurities. Hydrogen fluoride is added to dissolve beryllium hydroxide and produce fluoro beryllium acid solution. Then the ammonia gas is introduced to obtain ammonium fluoroberyllate crystals.

2010年11月28日 · The metal is produced by magnesium reduction of anhydrous beryllium fluoride. Reduction process yields beryllium metal in the form of pebbles. Metal pebbles are refined by vacuum induction melting. Vacuum cast ingot is further processed through powder metallurgy to produce vacuum hot pressed beryllium blocks.

2021年4月6日 · Electrorefining may be used (1) to produce high-purity metals and (2) to reclaim scrap metals in a useful, form. High-purity beryllium metal is desired for use in the nuclear field and in metallurgical research leading to the utilization of its favorable light weight and strength in …
