Product Description

Yttria Stabilized ZrO2 Sheet Crcuit Boards Zirconia Ceramic Plates Substrates


Product Introduction

Ceramic itself is a relatively brittle material, but because of the addition of zirconia, the toughness has been extremely improved. Due to the smooth 
surface advantage of ceramics, the friction coefficient is extremely low and it is not easy to wear. In addition, ceramics also have strong
corrosion resistance.

Zirconia ceramics 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.
