Poleiti ea ho Sila ea Alumina Ceramic e Hloekileng ka ho Fetisisa bakeng sa ho Lapping ka ho Sebetsa
St.Cera'spoleiti ea ho sila ea ceramice entsoe ka alumina ea 99.8% e hloekileng haholo (Al₂O₃) bakeng sa lits'ebetso tsa ho lata le ho sila ka nepo. Bokhoni ba rona ba ho sila ka nepo bo fihlella ho ba bataletseng ha 0.003mm, ho bapa ha 0.002mm, le qetello ea bokaholimo ba Ra0.1, ho netefatsa ho tlosoa ha thepa ka mokhoa o ts'oanang holim'a bokaholimo bohle ba poleiti. Poleiti e fana ka khanyetso e ntle ea ho tsofala (Vickers 16 GPa), matla a phahameng a ho kobeha (361 MPa), le botsitso ba mocheso ho fihlela ho 800°C. E fumaneha ka libopeho tse chitja ho fihlela ho bophara ba 600mm le lipoleiti tse khutlonnetsepa ho fihlela bolelele ba 1500mm. Libaka tse kobehileng (bophara ba groove 0.5–2.0mm) lia fumaneha bakeng sa kabo ea slurry lits'ebetsong tsa ho lata. Poleiti ka 'ngoe e hlahlojoa ka interferometer ea laser 'me e fanoa ka tlaleho ea tekanyo ea ho nepahala.
