Yog sintered tabular corundum, alumina hmoov ua cov khoom siv raw, tom qab zoo sib tsoo, molding, ziab, hauv qhov kub siab kub kiln (1800-1900 ºC), cov hluav taws kub ceev ceev ceev hauv cov xwm txheej ntawm lub tshuab ua kom txias txias, nws muaj qhov refractoriness, zoo thermal poob siab tsis kam thiab nkag tsis kam thiab tshiav tsis kam rau Al2O3 ntau lawm yog cov khoom siv tseem ceeb los ntawm kev kub siab kub ntawm tabular corundum, muaj siab purity, siv lead ua loj, me intracrystalline pores thiab dav faib, siab ntim loj, qis porosity, thiab lwm yam Nws qhia tau zoo heev thermal shock stability, lub zog siab thiab fluidity zoo hauv daim ntawv thov, yog li nws yog dav siv nyob rau hauv kev lag luam kub ntau yam xws li cov khoom siv refractory.As cov khoom siv tshiab, nws tau siv rau roj teeb anode cov ntaub ntawv, tshiab ceramics, hnub ci zog kev lag luam, ntsaws ruaj ruaj, tsheb thiab lwm yam kev lag luam.Ua tau paub rau txhua tus, phaj corundum ceramics yog siv rau kev ua kom muaj abrasives. Vim yog lub zog super zog ntawm emery ceramics, nws tuaj yeem npaj mus rau ntau yam kev sib tsoo lub log, emery daim ntaub, ntuab zeb thiab ntau yam abrasives, uas tau siv dav hauv cov tshuab ua cov khoom lag luam.Qhov corundum cov khoom kuj muaj qis kev coj tus kheej thiab kev sib txhuam coefficient. , uas yog kwv yees li ib nrab ntawm cov khoom siv cemented carbide. Nws cov thermal poob siab tsis kam thiab siab elastic modulus tau thov hauv qee qhov chaw tshwj xeeb. Piv txwv li, lub laser reflector siv los ua kom muaj zog loj yog qhov zoo dua li tooj liab hauv kev ua tau zoo vim nws qhov qis tsawg, zoo rigidity thiab deformation me.

Piv nrog fused alumina, tabular aluminahas cov lus qhia zoo hauv qab no:

1. Sintered phaj corundum muaj cov ntsiab lus tsis muaj qhov tsis muaj zog thiab qhov kev faib tawm yam tsis zoo, thaum electrofused corundum muaj cov ntsiab lus impurity siab thiab faib tsis ncaj.

2. Lub thermal poob siab tsis kam thiab qhov ua siab tshaj ntawm sintered phaj corundum zoo dua li ntawm fused alumina.

3. Cov txheej txheem ntau lawm ntawm sintered phaj corundum yog ntau lub zog txuag thiab kev tiv thaiv ib puag ncig dua li cov fused alumina.
