Polished Zirconium Oxide Substrate Precision Machining ZrO2 Zirconia Ceramic Sheet
Jinghui can produce polished zirconia ceramic sheets according to your requirements.
After precision processing and surface treatment, zirconia ceramic sheets have excellent physical, chemical and mechanical properties and are often used in electronics, medical care, aerospace and other fields.
Why Polished
After polishing of the ceramic substrate:
- A finer pattern can be obtained.
- Better parallelism of the upper and lower surfaces (thickness tolerance) can be achieved.
- A thinner metallization layer can be acquired.
