Zirocnia Ceramics:

At present, ceramic substrates for practical production and development applications include Al2O3, AlN, SiC, BeO, BN, mullite, and glass ceramics. Among them, BeO and SiC have high thermal conductivity (&sup3; 250W/mK), but BeO is toxic, the application range is small, so the yield is low; SiC has small volume resistance (<1013W·cm) and large dielectric constant. (40), high dielectric loss (50), is not conducive to signal transmission, and the molding process is complicated, the equipment is expensive, so the application range is also small; AlN ceramic substrate is a new generation of high-performance ceramic substrate, which is very high Thermal conductivity (theoretical value is 319W/mK, commercial AlN substrate thermal conductivity is greater than 140W/mk), lower dielectric constant (8.8) and dielectric loss (~4×104), and silicon The ratio of thermal expansion coefficient (4.4×10-4/°C), but due to the high cost, has not been applied on a large scale; Al2O3 ceramic substrate has a low thermal conductivity (20W/mK), but its production The process is relatively simple, the cost is low, and the price is cheap, which has become the most widely used ceramic substrate.
