I-Polycrystalline Diamond (PCD) iyi-polycrystalline corundum ehlanganiswe ngaphansi kwezinga lokushisa eliphezulu kanye nokucindezela okuphezulu Ivamise ukwakhiwa ukusabela kwamakhemikhali kwezinhlayiya zedayimane ezinosayizi we-micron ngaphansi kokushisa okuphezulu nokucindezela okukhulu. I-tabular corundum inobulukhuni obuphezulu kakhulu, ukumelana nokugqoka, ukuzinza kwamakhemikhali kanye ne-thermal conductivity Kuyinto ebalulekile yezinkambu zesicelo eziphezulu njengamathuluzi ahlukahlukene okusika, ama-abrasives kanye nezinto zokushisa ukushisa.
Okokuqala, i-corundum efana nepuleti inobunzima obuphakeme kakhulu, okwesibili kuphela kwedayimane lekristalu elilodwa, elinobunzima obungaphezu kuka-9000HV, obuphakeme kakhulu kunezinye izinto zensimbi nezingezona ezensimbi. Okwesibili, izinga lokugqoka le-corundum emise okwepuleti liphansi kakhulu Alikwazi ukuhlala libukhali isikhathi eside kuphela, kodwa futhi linciphisa ukugqoka kwezinto ezibonakalayo nokulahlekelwa ukushisa, ngaleyo ndlela kuthuthukisa ukusebenza kahle nokusetshenziswa kwamandla. Ngaphezu kwalokho, i-tabular corundum nayo inokumelana nokugqwala okuhle kakhulu kanye nokuzinza kokushisa, futhi ingasebenza ngokuzinza ngaphansi kwezinga lokushisa eliphezulu, ukucindezela okuphezulu kanye nezindawo ezigqwalile.
Emkhakheni wokukhiqizwa kwezimboni, i-tabular corundum inezinhlobonhlobo zezicelo. Isibonelo, emkhakheni wokucutshungulwa komshini, i-corundum ene-plate-shaped ingasetshenziselwa ukukhiqiza amathuluzi okusika ahlukahlukene, njengamathuluzi okuguqula, ama-milling cutters, ama-drill bits, ama-planers, amathuluzi okusika, ama-abrasives, njll, okungathuthukisa ngokuphumelelayo ukusika ukusebenza kahle kanye nekhwalithi yokusika. Emkhakheni wobuchwepheshe be-elekthronikhi, i-tabular corundum ingasetshenziselwa ukukhiqiza amadivaysi e-electronics anamandla amakhulu, amasinki okushisa, ukupakishwa kwe-LED, ukukhiqizwa kwe-semiconductor, njll, okungathuthukisa ukusebenza kahle kokusebenza nokuphila kwamadivayisi kagesi. Ngaphezu kwalokho, i-tabular corundum ingase isetshenziselwe ukukhiqiza ama-reactors amakhemikhali ahlukahlukene, ama-high-temperature nemikhumbi yokucindezela okukhulu, njll., engasebenza ngokuzinzile ngaphansi kokushisa okuphezulu, ukucindezela okuphezulu kanye nezindawo ezibolayo.
Ngamafuphi, i-tabular corundum iyimpahla esebenza kakhulu ebaluleke kakhulu izici zayo ezinhle kakhulu zomzimba namakhemikhali kanye namathemba okusebenza abanzi aletha amathuba angenamkhawulo wokuqanjwa kabusha kwesayensi nezobuchwepheshe kanye nokuthuthukiswa kwezimboni.
