Detailed Product Description
Ceramic knife is a made out of very hard ceramic.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 till the firing process. Like all ceramics these are consolidated into a dense and strong ceramic by solid state sintering at approximately 1400 degree Celsius for 5-12 hours in a high temperature furnace. The result is a very tough 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.
