Common problems of alumina ceramics

Does alumina ceramic absorb water?

  Answer: Whether the ceramic absorbs water is judged whether it is processed by high temperature sintering process, usually the water absorption rate of ceramic is ≥5%.


  Is alumina ceramic conductive?

  Answer: AI2O3 ceramics have excellent electrical insulation performance, and the voltage resistance is as high as 80,000V/mm. If it is broken by high voltage, its volume resistivity will drop rapidly.


  Is alumina ceramic toxic?

  Answer: AI2O3 ceramics are completely non-toxic and harmless, environmentally friendly ceramic materials, which can be used in ceramics, knives, tableware, parts, tools and other ceramic products in life.


  Is alumina ceramic fragile?

  Answer: The toughness of most ceramics is low, which is also the main reason for the brittleness of ceramics; toughness technology can be used to increase the toughness of ceramic products and reduce the occurrence of chipping of ceramic products. The commonly used ceramic toughening technologies include phase change toughening , Crack toughening, fiber toughening and particle toughening, etc.
