Processing of germanium

Physical and chemical properties

This is a rather brittle metal, up to 550 °C it is not accessible to pressure treatment. Covered with oxide film, it is quite stable under normal conditions to water, air, hydrochloric acid, almost does not interact with caustic alkalis, but dissolves in alkaline solution of perhydrol and in aqua regia. Its valence is +2 or +4. Chemical compounds with higher valency are more stable.

Mechanical processing

Mechanical processing of germanium is carried out in accordance with the principles of working with solid materials. Cutting and grinding is done with a diamond cutter. In order to increase the cutting capacity, as a rule, a CNC lathe with special cutters (for example, BK8 brazing inserts) is used. Cutting ingots into blanks can be done with circular saws. Cleanliness of the surface during turning is achieved by a low feed and the use of a special lubricating fluid coolant.

Machining with ultrasound

Machining with ultrasound is also common - it avoids microcracks and reduces surface roughness.

Chemical treatment

Regarding chemical treatment - all rare metals, require multistage treatment, taking into account the peculiarities of interaction with acids and alkalis.
