Yleiskatsaus
Fysikaaliset ja kemialliset ominaisuudet
It has the characteristics of high strength, high hardness, wear resistance and corrosion resistance.
(1) High thermal conductivity (about 320W/m K), close to BeO and SiC, more than 5 times that of Al2O3;
(2) The thermal expansion coefficient (4.5×10-6°C) matches Si (3.5-4×10-6°C) and GaAs (6×10-6°C);
(3) Excellent electrical properties (dielectric constant, dielectric loss, volume resistivity, dielectric strength);
(4) Good mechanical properties, higher flexural strength than Al2O3 and BeO ceramics, and can be sintered at normal pressure;
(5) Good optical transmission characteristics;
(6) Non-toxic
