Main characteristics of Ignition Ceramic Rods
1. High electrical insulation with high voltage resistance up to 18KV at least
2. Great mechanical properties with diamond-like hardness, not easy to break
3. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like H2SO4
4. Smooth surface with well-distributed glaze, it could strengthen the insulation further
The Description of alumina ceramics
Aluminum Oxide Ceramic is widely used in many fields including mechanical, electronics, electrical, automotive, semiconductor, textile, etc. For good properties, more and more customers choose Alumina ceramic materials for their applications. Alumina Ceramic can be made to Ceramic Nozzles, Ceramic Sprayers Cyclones, Ceramic Linings, Milling Systems, Ceramic Thread guides, etc. Customized designs are very often to be made.
