A ceramic knife is a knife made out of very hard ceramic, often zirconium oxide (ZrO2). These knives are generally produced by compacting Zirconia powder using high pressure presses which apply a pressure of around 300 tons to produce blade shaped blanks. These blanks are very brittle and fragile which can be shattered by a slight blow and special binders are used to retain the shape of the blank until the firing process. Like all ceramics these are consolidated into a dense and strong ceramic by solid state sintering at approximately 1400 degrees centigrade for 5–12 hours in a high temperature furnace. The result is a very tough[citation needed] and blunt blade which needs to be sharpened to get the desired cutting edge. The blades are sharpened by grinding the edges with a diamond dust coated grinding wheel.

Zirconia is very hard; it ranks 8.5 on the Mohs scale of mineral hardness, compared to 6 to 6.5 for hardened steel, and 10 for diamond, giving a very hard edge that rarely needs sharpening. However, when sharpening is needed, they cannot be resharpened the same way as steel blades, which are often sharpened with a ceramic whetstone. To sharpen the edge of a blade a material harder than the one that is being sharpened is required, and ceramic knives are usually sharpened with industrial grade diamond sharpeners.

What are the reasons behind Kyocera Advanced Ceramic’s success?

Kyocera Advanced Ceramics is a part of Kyocera Corporation that came into existence in the year 1959. Kyocera Advanced Ceramics are the world’s biggest manufacturers of innumerable kitchen cutleries, ceramic knives and several stationery products.

Ceramics like zirconium are hardest elements next to diamonds in front of which the regular metal knives cannot match. Moreover, Kyocera ceramic knives do not contain only ceramics. The Kyocera knives contain advanced ceramics-the ceramics that are processed to increase their density and hardness. Kyocera Advanced Ceramics believe in manufacturing novel kitchen tools to give the people a whole new cooking experience.
