Alumina (Al2O3)
Lub Precision tej yam uas tsim los ntawm ZHonghui Intectionic Pab Pawg (Zhhimg) tuaj yeem ua los ntawm High-Purity Ceramina, 99.9% Alumina, thiab CIP CARUETICS TIBSICING. Siab kub sintering thiab precision machining, qhov sib npaug raug ntawm ± 0.001 hli, siv ntsuas kub txog li 1600 degrees. Different colors of ceramics can be made according to customers' requirements, such as: black, white, beige, dark red, etc. The precision ceramic parts produced by our company are resistant to high temperature, corrosion, wear and insulation, and can be used for a long time in high temperature, vacuum and corrosive gas environment.

Ntawm tam sim no, txhuas oxide ceramics tuaj yeem faib ua cov kev coj dawb huv thiab cov ceramics. Lub siab huv txhuas oxide ceramics series hais txog cov khoom siv ceramic muaj ntau dua 99.9% al₂o₃. Vim tias ntawm nws sintering kub txog li 1650 - 1990 ° C thiab nws cov kis tau los ntawm fuse cov raj thiab corrosion tsis kam rau alkali hlau. Hauv kev lag luam hluav taws xob, nws tuaj yeem siv los ua cov khoom siv insulating high-zaus insulating rau IC substrates. Raws li cov ntsiab lus sib txawv ntawm txhuas oxide, cov khoom siv txhuas oxide series tuaj yeem faib ua 99 ceramics, 95 ceramics, 90 ceramics thiab 85 ceramics. Qee zaum, cov lus ceramics nrog 80% lossis 75% ntawm txhuas olide kuj tseem tau cais ntau li txhuas oxide series. Ntawm lawv, 99 aluminium oxide cov khoom siv yog siv los tsim cov khoom tawg loj, cov khoom siv hluav taws xob muaj hluav taws xob, xws li cov pob zeb ceramic, ceramic ntsaws ruaj ruaj. 95 Txhuas Ceramics yog tsuas yog siv raws li corrosion-resistant hnav-resisting feem. 85 ceramics feem ntau sib xyaw ua ke hauv qee cov khoom, yog li kev txhim kho hluav taws xob ua tau thiab lub zog kho tshuab. Nws tuaj yeem siv Molybdenum, niobium, tantalum thiab lwm cov ntsaws ruaj ruaj, thiab qee qhov siv los ua cov khoom siv hluav taws xob nqus.
