Sanda mai kyau na Alumina don Semiconductor Fixes
Sanda mai siffar serami na St.Cera an niƙa shi daidai gwargwado daga alumina mai tsarki mai ƙarfi 99.8% (Al₂O₃). Yana ba da tauri mai yawa (16 GPa), juriya mai kyau ga lalacewa, da kwanciyar hankali. Yana jure wa diamita mai ƙarfi kamar ±0.005 mm, tsawonsa har zuwa 150 mm. Ana lanƙwasa saman sandar zuwa Ra ≤0.2 μm don sakawa da cirewa mai santsi. Ana amfani da shi azaman fil ɗin daidaitawa, fil ɗin dowel, ko tsayawar sanyawa a cikin kayan aikin semiconductor, cassettes ɗin wafer, da kayan aikin dubawa.
