<br>Remark -- ceramic knife knowledge:
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. Like all ceramics these are consolidated into a dense and strong ceramic by solid state sintering at approximately 1400 degrees centigrade for 5 to 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.
<br>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. ceramic knives are usually sharpened with industrial grade diamond sharpeners.
<br>The highest strength and more importantly toughest zirconia is produced with 3 mol% yttrium oxide yielding partially stabilized zirconia. This material consists of a mixture of tetragonal and cubic phase with a bending strength of nearly 1200MPa.
<br>Ceramic knives will not rust, leading to their use by SCUBA divers. Their chemical inertness to both acids and alkalis and their ability to retain a cutting edge far longer than forged metal knives, makes them a very good culinary tool for slicing and cutting through boneless meat, vegetables and fruits. Since they are very rigid they cannot be used for chopping, cutting bones or frozen foods or prying open things, which may cause the cutting edge to chip off or the blade to break free from the handle. The tips of these knives are resistant to rolling and pitting but may break when dropped to the ground.
