♦Alumina(Al2O3)
Izingxenye ze-ceramic ezinembayo ezikhiqizwe i-ZhongHui Intelligent Manufacturing Group(ZHHIMG) zingenziwa ngezinto ezingavuthiwe ze-ceramic ezihlanzekile kakhulu, i-92~97% i-alumina, i-99.5% ye-alumina, > i-99.9% ye-alumina, kanye nokucindezela okubandayo kwe-isostatic kwe-CIP.Ukushisa okuphezulu kwe-sintering kanye nokwenza imishini enembayo, ukunemba kwe-dimensional okungu-± 0.001mm, ukushelela kufika ku-Ra0.1, sebenzisa izinga lokushisa elifika ku-1600 degrees.Imibala ehlukene ye-ceramics ingenziwa ngokuvumelana nezidingo zamakhasimende, njengokuthi: omnyama, omhlophe, beige, obomvu obumnyama, njll. Izingxenye eziqondile ze-ceramic ezikhiqizwa inkampani yethu zimelana nokushisa okuphezulu, ukugqwala, ukuguga kanye nokufakwa kwe-insulation, futhi kungaba esetshenziswa isikhathi eside endaweni yokushisa ephezulu, i-vacuum negesi egqwalayo.
Isetshenziswa kakhulu kumishini ehlukahlukene yokukhiqiza i-semiconductor: Amafreyimu (ubakaki beceramic), I-Substrate (isisekelo), Ingalo/Ibhuloho(i-manipulator), , Izingxenye Zemishini kanye Ne-Ceramic Air Bearing.

Ukusetshenziswa kwe-alumina ceramics yokuhlanzeka okuphezulu:
1. Kufakwe kumishini ye-semiconductor: i-ceramic vacuum chuck, i-cutting disc, i-disc yokuhlanza, i-CHUCK ye-ceramic.
2. Izingxenye zokudluliswa kwe-wafer: ama-chucks okuphatha i-wafer, ama-disc okusika ama-wafer, ama-disc wokuhlanza ama-wafer, izinkomishi zokuhlola optical zokudonsa.
3. LED / LCD flat panel display industry: ceramic nozzle, ceramic grinding disc, LIFT PIN, PIN rail.
4. Ukuxhumana okubonakalayo, imboni yelanga: amashubhu e-ceramic, izinduku ze-ceramic, ibhodi lesifunda lokunyathelisa isikrini se-ceramic scrapers.
5. Izingxenye ezikwazi ukumelana nokushisa nezivimbela ugesi: ama-ceramic bearings.
Njengamanje, ama-ceramics e-aluminium oxide angahlukaniswa abe ubumsulwa obuphezulu kanye ne-ceramics evamile.Uchungechunge oluphezulu lwe-aluminium oxide ceramics oluhlanzekile lubhekisela ezintweni ze-ceramic eziqukethe ngaphezu kuka-99.9% Al₂O₃.Ngenxa yokushisa kwayo okushisayo okufika ku-1650 - 1990°C kanye nobude bayo bokudluliswa kwegagasi obungu-1 ~ 6μm, ivamise ukucutshungulwa ibe ingilazi ehlanganisiwe esikhundleni se-platinum crucible: engasetshenziswa njengeshubhu le-sodium ngenxa yokudlulisa ukukhanya nokumelana nokugqwala. insimbi ye-alkali.Embonini ye-elekthronikhi, ingasetshenziswa njengezinto zokuvikela imvamisa ephezulu zama-IC substrates.Ngokusho kokuqukethwe okuhlukile kwe-aluminium oxide, uchungechunge olujwayelekile lwe-aluminium oxide ceramic lungahlukaniswa ngama-ceramics angama-99, ama-ceramics angama-95, ama-ceramics angama-90 nama-ceramics angama-85.Kwesinye isikhathi, izitsha zobumba ezinama-80% noma 75% we-aluminium oxide nazo zihlukaniswa njengochungechunge olujwayelekile lwe-aluminium oxide ceramic.Phakathi kwazo, i-99 aluminium oxide ceramic material isetshenziselwa ukukhiqiza i-crucible high-temperature, ithubhu yesithando somlilo kanye nezinto ezikhethekile ezivimbela ukugqokwa, njengama-ceramic bearings, seals se-ceramic namapuleti e-valve.I-95 aluminium ceramics isetshenziswa kakhulu njengengxenye emelana nokugqwala.I-ceramics engu-85 ivame ukuxutshwa kwezinye izakhiwo, ngaleyo ndlela ithuthukise ukusebenza kukagesi namandla emishini.Ingasebenzisa i-molybdenum, i-niobium, i-tantalum nezinye izigxivizo zensimbi, kanti ezinye zisetshenziswa njengamadivaysi kagesi e-vacuum.
