Melemo ea Setsebi
1. E ikhethang Thermal Stability
- Sebaka se qhibilihang: 2,730 ° C (e tšehetsa maemo a mocheso o phahameng haholo)
- Ho hanyetsa oxidation ho fihla ho 1,600 ° C moeeng (e thibela ho senyeha ha maemo a leholimo a oxidative)
2. Superior Thermal Conductivity
- 150 W/(m·K) mocheso oa mocheso oa mocheso oa kamore (e nolofalletsa ho fetisa mocheso ka potlako le kabo e tšoanang ea mocheso)
- E fokotsa tšebeliso ea matla ka 20-30% ha e bapisoa le lisebelisoa tsa khale tsa refractory.
3. Ho hanyetsana le Thermal Shock Resistance
- E mamella ho feto-fetoha ha mocheso ka potlako ho feta 500 ° C/sec (e loketseng bakeng sa ho futhumatsa / ho bata ka baesekele).
- E boloka botšepehi ba sebopeho tlas'a baesekele e futhumetseng (e thibela ho phunyeha le ho senyeha).
4. Matla a Phahameng a Mechini ka Lithempereichara tse Phahameng
- E boloka 90% ea matla a mocheso oa kamore ho 1,400 ° C (a bohlokoa bakeng sa likarolo tsa sebōpi se jereng meroalo).
- Ho thatafala ha Mohs ea 9.5 (ho hanana le ho roala ho tloha linthong tse senyang libakeng tsa sebōpi).
