I believe that in the impression of many friends, ceramics, a hard and brittle material, have always been used to make containers, tableware, tiles, decorations and other products. I don’t know if you have understood that ceramics can also be made into knives? In fact, ceramic knives have a history of nearly a hundred inventions. Ceramic knives have now developed into a product with very mature technology, and many families are currently using it. ceramic knife.
For traditional metal knives, although it can meet most of the cutting needs in family life, there are still many shortcomings.
For example, metal knives are easy to rust and have poor wear resistance. After a long time, they are easy to rust and become blunt, which is very inconvenient in many cases. It is under this condition that ceramic knives came into being.
The material used in ceramic knives is not the ceramics fired from natural soil that is common in our lives, but the modern high-tech special ceramics that are artificially synthesized.
As early as 1912, some European and American countries used alumina as raw material to produce alumina ceramic knives, but due to its low performance, it was not recognized by the society. It was not until 50 years later that people invented the composite alumina material. The strength and toughness of ceramic knives made of this material have been greatly improved, and ceramic knives have gradually entered people's field of vision since then. By the early 1980s, silicon oxide ceramic knives had come out. This ceramic knives material was very close to modern ceramic knives materials, and the sales of ceramic knives in developed countries began to rise continuously.
With the continuous development of synthetic technology, more and more synthetic materials are used to make ceramic knives. The common ceramic knives currently on the market use zirconia as the raw material, and use zirconia powder with a molecular size of nanometers to bake at a high temperature of more than 2,000 degrees, and apply a high pressure of more than 300 tons to the mold to make it. Able to produce blanks of zirconia knives. The knife blank is then finely ground by diamond to make a ceramic knife blade.
The performance of zirconia ceramic knives is unmatched by traditional white ceramic knives. The zirconia material not only greatly improves in strength, hardness, toughness and other aspects, but also has the advantages of corrosion resistance, wear resistance and high temperature resistance. significantly. These advantages greatly broaden the scope of use of zirconia ceramic knives, not only can cut and process high-hardness materials according to different precision requirements, but also can perform high-speed cutting, and even continuous cutting at high temperatures above 1,000 degrees. It is something that traditional ceramic knives cannot do. In addition, zirconia is also called "zircon gemstone" because of its elegant and precious appearance, and it can be described as a well-deserved "noble knife".
