1. Botsitso bo ikhethang ba Thermal
- Sebaka sa ho qhibiliha: 2,730°C (e boloka tikoloho e nang le mocheso o phahameng haholo)
- Ho hanyetsa oxidation ho fihlela ho 1,600°C moeeng (ho thibela ho senyeha ha moea o nang le oxidation)
2. Ho Tsamaisa Mocheso ka Botlalo
- 150 W/(m·K) conductivity ea mocheso mochesong oa kamore (e nolofalletsa phetiso ea mocheso ka potlako le kabo ea mocheso o ts'oanang)
- E fokotsa tshebediso ya matla ka 20–30% ha e bapiswa le thepa ya setso e hanyetsang.
3. Khanyetso ea Tšabo ea Thermal e sa Bapisoeng
- E mamella ho feto-fetoha ha mocheso ka potlako ho feta 500°C/sec (e loketse lits'ebetso tsa ho futhumatsa/ho pholisa ka potoloho).
- E boloka botsitso ba sebopeho tlas'a potoloho ea mocheso (e thibela ho petsoha le ho fetoha ha sebopeho).
4. Matla a Phahameng a Mechine Maemong a Phahameng a Thempereichara
- E boloka 90% ea matla a mocheso oa kamore ho 1,400°C (e bohlokoa bakeng sa likarolo tsa ontong tse jarang mojaro).
- Bothata ba Mohs ba 9.5 (bo hanela ho tsofala ha thepa e kgopang tikolohong ya ontong).

Ka ho nkela likarolo tsa alumina tse tloaelehileng sebaka kali-nozzle tsa silicon carbide burner, kgwebo e tlalehile:
✅ Litšenyehelo tsa tlhokomelo tsa selemo le selemo tse tlase ka 40% ka lebaka la ho fokotseha ha tšenyo ea likarolo tikolohong ea 1500°C+.
✅ Keketseho ea 20% ea nako ea tlhahiso, e susumetsoang ke ho hanyetsa ha SiC ho ts'oha ha mocheso le mafome a tsoang ho slag e qhibilihisitsoeng.
✅ Ho tsamaisana le maemo a taolo ya eneji a ISO 50001, ho sebedisa matla a phahameng a SiC a ho tsamaisa motlakase ho ntlafatsa bokgoni ba mafura ka 15–20%.
