Ceramic Rings Overview

Ceramic rings, washers, seals, bearings, and bushings are generally used as the gap / insulation / bearing application. They offer excellent electrical insulation, high abrasion resistance, and high hardness. Our ceramic rings are formed by CIP (Cold Isostatic Pressing) and dry pressing. The CIP process provides enhanced strength particularly.

The main materials used are alumina (Aluminium Oxide, Al2O3),  this material ensures high mechanical strength resistance, high wear resistance, high heat resistance, excellent strength and thermal stability in harsh environments. It has been widely used in engineering, mechanical seals, automotive, electronics, instrumentation, sensing, and other industries.

Available Materials

※ Porous ceramics are not available for us, all of our ceramics are made of non-porous ceramic material

※ Alumina (Al2O3 Aluminium Oxide), purity: 95%, 96%, 97%, 98%, 99%, 99.5%, 99.7%, 99.9%, 99.99%

※ ZTA (Zirconia Toughened Alumina)

※ Zirconia (ZrO2, Zirconium Oxide) and YSZ (Yttria-stabilized Zirconia)

※ Silicon Nitride (Si3N4) and Silicon Carbide (SiC)
