A process for preparing thin-walled molded parts made of ceramic and by the method for sound transducer membrane obtained

摘要

the invention concerns a method of producing thin walled molded from ceramics. this is the desired molded from reinaluminium formed and as long as one anodic oxidation to the subject to reinaluminium largely aluminium oxide has become.the aluminium oxide existing part is then at temperatures above 600 degrees celsius, so long as fire, to the aluminum oxide in a crystalline modification transformed. by using the method can, for example, membrane for loudspeaker manufacture.
