Abstract

The invention provides a method for preparing germanium dioxide (GeO2). According to the embodiment of the invention, the method comprises the following steps: hydrolyzing the germanium tetrachloride(GeCl4) in a fully-closed hydrolysis reactor to obtain the hydrolysis product of the GeCl4, centrifuging and filtering the hydrolysis product of the GeCl4 to obtain the GeO2 and the filtrate, and cleaning the GeO2 by high-purity water to obtain the high-purity GeO2 and the cleaning solution. According to the embodiment of the invention, the GeO2 hydrolyzing, filtrating and washing method and device have the advantages of high degree of automation, high GeO2 hydrolysis yield, good solid-liquid centrifugal separation effect, low production costs, less metal loss and environment friendliness.

Description

technical field [0001] The invention relates to the field of metallurgy, and more specifically, the invention relates to a new method and device for preparing germanium dioxide from germanium tetrachloride. Background technique [0002] In germanium extraction technology, germanium concentrate is used as raw material to obtain high-purity GeO through chlorination distillation, double steaming, rectification, hydrolysis, filtration, drying, and calcination. 2 product. Among them, high-purity germanium tetrachloride is hydrolyzed with ultra-pure water to produce solid GeO 2 and hydrogen chloride mixture, in order to obtain high-purity GeO with qualified purity and particle size 2 Products, the hydrolysis reaction temperature must be strictly controlled, so that the temperature is not too high or too low to cause GeO 2 The particle size is not uniform, and the germanium dioxide and the filtrate are separated by means of filtration. [0003] However, the current method for p...
