Research and Application of New Drying Process for Germanium Dioxide

Abstract:

Oven drying and microwave drying processes for GeO₂ after hydrolysis and filtration of GeCl₄ were performed, and then the polymorphs, surface morphology and chemical composition, etc. of GeO₂ were analyzed. The influence of microwave power and material thickness to GeO₂ moisture removal rate was researched in a single-factor-based test. The gained optimum process parameters for microwave drying GeO₂ are as below: microwave power is 400~550 W, material thickness for each time is 30~40 mm, and drying time for 1 kg GeO₂ is 36.67~40.00 mins. The results show that through the two processes, they can both gain GeO₂-06 products meeting national standard, and compare with them to obtain that microwave drying has the advantages of high efficiency, low energy consumption, no caking, etc.
