Zirconia ceramic tools have the characteristics of high strength, wear resistance, no oxidation, no rust, acid and alkali resistance, anti-static, and no reaction with food. At the same time, the blade body is as shiny as jade, which is the ideal high-tech green in the world today. Knives, the current main products in the market are: zirconia ceramic table knives, scissors, razors, scalpels, etc. In recent years, it has become popular in Europe, the United States, Japan, South Korea and other places. Zirconium oxide high-temperature heating material Zirconia is an insulating material at room temperature, with a specific resistance of up to 1015Ω·cm. When the temperature is increased to 600°C, it can conduct electricity, and it is a good conductor when it is above 1000°C. The temperature can reach 2400°C, and it has been successfully used in heating elements and equipment under an oxidizing atmosphere above 2000°C. Electrode materials for magnetic fluid power generation are also under active research.
