Mkpanaka Ebe Alumina Ceramic nke Alumina maka Ihe Ndị Na-enye Semiconductor
A na-eji ígwè seramiiki nke St.Cera mee ka ọ dị ọcha nke ukwuu site na 99.8% alumina dị ọcha (Al₂O₃). Ọ na-enye ike siri ike (16 GPa), ezigbo ike iyi, na nkwụsi ike nha. O siri ike dịka ±0.005 mm, ogologo ya ruru 150 mm. A na-etinye elu mkpanaka ahụ ruo Ra ≤0.2 μm maka ntinye na iwepụ ya nke ọma. A na-eji ya dị ka ntụtụ nhazi, ntụtụ dowel, ma ọ bụ nkwụsị nhazi na ihe ndozi usoro semiconductor, kaseti wafer, na ngwa nyocha.
