1. High hardness: Lub hardness Mohs ntawm qhov chaw ncav cuag qib 7.

2. High compressive zog, siab tensile zog. Tsis muaj xim dawb, tsis muaj deformation thiab tsis tawg txawm tias nws raug tshav ntuj. Qhov tshwj xeeb feature ua rau nws dav siv hauv pem teb tso.

3.Zero thermal expansiontuav cov qauv kev ncaj ncees thoob plaws qhov kub thiab txias (-18 ℃ to 1000 ℃), khaws cia qhov loj me, xim, thiab cov duab ruaj khov.

4.Superior tshuaj tiv thaivtiv thaiv corrosion, acids, thiab alkalis kom tsis muaj fading los yog lub zog degradation dhau ntev raug.

5. Tsis muaj dej thiab av nqus. Nws yog ib qho yooj yim thiab yooj yim los ntxuav.

6. Tsis yog-radioactive, ib puag ncig tus phooj ywg thiab rov siv tau.
