Product Description

China Factory Machined Industrial Custom Technical Alumina Ceramic End Effector

The main features of the semiconductor ceramic end effector
1. High precision dimensions with tightening tolerance, it's easier to get a perfect fitting relationship
2. High-temperature ability: withstand up to 1650°C in oxidizing and reducing atmospheres
3. Wear & abrasion resistance: Alumina is extreme hard technical ceramic with superb wear resistance
4. Chemical inertness, resistant most of the strong acid and alkali, and does not rust forever 
5. Electrical insulation: The insulation breakdown is up to 18KV at least
6. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
7. Chemical corrosion resistance under high temperature, even if with strong acid or alkali
8. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.
9. Low material cost in high-level applications than other technical ceramics

The description of high precision alumina ceramic end effector
For semiconductor devices, the critical process, as well as the parts which need to be used in a vacuum, high temperature, and corrosive gas environment, also require a clean and dustless environment. However, precision ceramic material could maintain high stability in a complicated physical and chemical environment. Semiconductor ceramic part we produced with wear resistance, corrosion resistance, low thermal expansion, insulation is made from 99.8% alumina ceramic and formed by cold isostatic pressing, high-temperature sintering, and precision machining, that's why can meet the stringent requirements of parts for semiconductor equipment.
