Abstract

The invention discloses a quartz tube cleaning process for growth of cadmium zinc telluride. The cleaning process comprises the following steps: firstly, sanding a quartz tube by sanding paper; then,corroding reaction residues by using a bromomethanol solution, and combining ultrasound treatment to enhance erosion of bromomethanol on the reaction residues and increase the cleaning rate under mechanical action and cavitation action of ultrasound; finally, performing ultrasound treatment in sodium hydroxide. In order to relieve surface roughness of quartz and ensure smoothness of final cleaning, the whole method is simple to operate, avoids the use of hydrofluoric acid, and adopts ultrasound, so that the use of chemical reagents is reduced, and cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of quartz tube cleaning, in particular to a process for cleaning a quartz tube for growing cadmium zinc telluride. Background technique [0002] Quartz tubes are made of silicon dioxide, which has stable chemical and physical properties. It is usually used as a reaction vessel for high-temperature reactions. Since the raw materials are heated during the reaction, traces of reactants will be left on the quartz tube. After the reaction, the quartz tube needs to be thoroughly washed before it can be used. [0003] At present, the cleaning of quartz tubes is mostly manual operation. The quartz tubes are soaked in a horizontal pickling tank with hydrofluoric acid, rinsed with a large amount of water after soaking, and then dried. The above-mentioned cleaning method not only wastes water resources, but also has certain damage to the operating personnel, and the quartz test tube after cleaning will have residual a...
