With the modern people's living standards improve the quality of daily necessities in life, the higher the requirements, including the usual use of tableware, zirconia ceramic cutting tools and chopsticks sought after by people. Zirconia ceramic with high toughness, high flexural strength and high wear resistance, excellent thermal insulation properties, thermal expansion coefficient close to the advantages of steel, with it made out of the tableware environmental protection, safety, zirconia ceramic hardness in the end is how much you do you know?
Zirconia ceramic hardness is very high, do the tool 3Y zirconia hardness test report to the data is greater than 9, second only to the diamond argument is correct, the diamond hardness should be defined 10, the hardness of the crystal should be 7 or so, without the hardness of zirconia.
The molecular weight of pure zirconia is 123.22, the theoretical density is 5.89g / cm3, and the melting point is 2715 ℃. Usually containing a small amount of hafnium oxide, it is difficult to separate, but the performance of zirconia no significant impact. Zirconia has three crystal forms: monoclinic, tetragonal, cubic crystal phase. At room temperature zirconia only monoclinic phase appears, heated to 1100 ℃ or so into a tetragonal phase, heated to a higher temperature will be converted into cubic phase.
Zirconia ceramic tool with high strength, wear resistance, no oxidation, no rust, Naisuan Jian, anti-static, will not react with the characteristics of food, while the body shiny jade, is the ideal of today's world of high-tech green Tools, the current market main products are: zirconia ceramic knives, scissors, razors, scalpels, etc., has been successfully used for more than 2000 ℃ oxidative atmosphere of the heating element and its equipment, the magnetic fluid power electrode Materials are also being actively studied.
