White zirconia hollow rod ZrO2 ≥ 95% the surface is smooth and shiny electronic manufacturing textile industry
product name:White zirconia hollow rod
model:HY-YH04
Product description:
Zirconia ceramics are mainly composed of zirconium dioxide ( ZrO2 ). At room temperature, it is a material with high mechanical strength and strong fracture toughness among all the main precision ceramics. It has high strength, hardness, high temperature resistance, acid and alkali corrosion resistance, good biocompatibility and high chemical stability. It has excellent scratch resistance, no signal shielding, excellent heat dissipation performance, strong processability, good appearance effect, and is very suitable for mass production. With its good performance characteristics, zirconia ceramics have relatively high-end applications and higher added value of products. The fields involved are : 3C electronics such as mobile phones, intelligent wearable fields, optical communication fields, biomedical fields, automotive fields, jewelry fields, daily life fields and other fields. It is also an important part of our lives.
