Jinghui has 18 years of experience in the production of bare ceramic substrates. Our products have high cost performance and will definitely satisfy you.
Zirconia ceramic plates have low thermal conductivity, but they have high hardness, good wear resistance and corrosion resistance, high toughness and high temperature resistance.
It has a very high melting point and is one of the best refractory materials in nature, so it can be perfectly competent in some mobile facilities with frequent vibrations and ultra-high temperature working environments. For example, rail transit semiconductor low-power modules and aerospace generator modules.
