Phaj Sib Tsoo Alumina Ceramic Uas Muaj Peev Xwm Siab Rau Kev Sib Tsoo Uas Muaj Kev Ntsuas Zoo
St.Cera'sphaj sib tsoo ceramicyog tsim los ntawm 99.8% alumina purity siab (Al₂O₃) rau kev siv lapping thiab kev sib tsoo kom raug. Peb lub peev xwm sib tsoo kom raug ua tiav qhov tiaj tiaj ntawm 0.003mm, parallelism ntawm 0.002mm, thiab qhov tiav ntawm Ra0.1, ua kom ntseeg tau tias cov khoom tshem tawm sib xws thoob plaws tag nrho cov phaj nto. Lub phaj muaj kev tiv thaiv kev hnav zoo heev (Vickers 16 GPa), lub zog flexural siab (361 MPa), thiab thermal stability txog li 800 ° C. Muaj nyob rau hauv cov qauv puag ncig txog li 600mm txoj kab uas hla thiab cov phaj rectangular txog li 1500mm ntev. Cov nto grooved (qhov dav groove 0.5–2.0mm) muaj rau kev faib cov slurry hauv cov txheej txheem lapping. Txhua lub phaj raug tshuaj xyuas nrog laser interferometer thiab muab nrog daim ntawv qhia kev ntsuas qhov tseeb.
