ABSTRACT:
Two parts, such as a quartz part and piezo-electric part, are indirectly connected to one another by applying relatively thin metallic layers having a thickness of about 0.5 nm to 55 nm under vacuum conditions onto the surfaces of such parts to be joined and then without ventilation of the vacuum-chamber contacting the free surfaces of such metallic layers with one another under the maintained vacuum conditions whereby a substantially permanent bond is formed between such layer.
