Novel extraction process method for purifying germanium tetrachloride

Abstract

The invention discloses a novel extraction process method for purifying germanium tetrachloride. Purification is the subject of the germanium metallurgical industry. The method is combined with an extraction theory, and a novel germanium tetrachloride purification process is researched through experiments. The dissolving situations of substances such as AsCl3 and the like in hydrochloric acid and GeCl4 differ greatly, and the aim of purifying GeCl4 can be fulfilled by extracting substances such as AsCl3 and the like in crude GeCl4 by taking the hydrochloric acid as an extracting agent. Conventional extraction is used for extracting active ingredients in a mixture. In recent years, an extraction method is used for purification. Full and effective mixing of the extracting agent and an extracted substance is a relatively key problem. High-speed spray is an effective method which can fully mix the extracting agent and the crude GeCl4. The experiments prove that the quantity of low-resistance germanium ingots can be reduced greatly by adding the process into the conventional technical condition, so that product percent of pass is increased to 90 percent.

Description

Technical field: [0001] The invention relates to a novel extraction process for purifying germanium tetrachloride. Background technique: [0002] With the development of modern science and technology, germanium is widely used in military affairs, medicine, health care, chemical industry, etc., especially in recent years, with the rapid development of optical fiber and solar energy industry, high-purity fiber-grade germanium tetrachloride has become more and more popular. attention. This puts forward higher requirements for the purification and production of high-purity intermediate germanium tetrachloride. Extraction, as a chemical purification method developed in the 1970s and 1980s, was first applied to the treatment of various low-grade ores. The purpose is to make the useful components that need to be recovered in low-grade ores enter the liquid phase to achieve purpose of separation. In the process of applying the extraction method, a large number of practices and ex...
