About Ceramic

The modern ceramic materials for jewelry making are the mixture of zirconia ceramic powder and appropriate amount of cementing agents. The mixture is injected into sealed moulds and then condensed through high temperature sintering to create the core shape. Ceramic materials are brittle, hard, strong in compression, weak in shearing and tension. They withstand chemical erosion that occurs in an acidic or caustic environment.

Ceramic materials are valued for their abrasion resistance. They find use in applications such as the wear plates of crushing equipment in mining operations. Ceramic is first used in watchmaking for producing watch cases for its light weight, scratch-resistance, durability and smooth touch. Jewelry makers see the same benefits of these materials and craft scratch-resistive ceramic rings. Ceramic rings are a lot like Tungsten Carbide rings in that they are scratch resistant against most materials. However, the ceramic ring will crack and smash if heavily abused.
