Characteristics of ceramic honeycomb

  • Honeycomb structure. Ceramic honeycomb block refractories are named for their honeycomb-like structure, which has a very high specific surface area, which improves its adsorption and reaction properties.
  • High-temperature stability. This type of refractory material is usually based on high-temperature ceramic powder and sintered at high temperatures. It has excellent high-temperature stability and can maintain stable performance in extremely high-temperature environments.
  • Excellent heat insulation and sound insulation performance. The unique structure of the ceramic honeycomb block makes it outstanding in thermal and sound insulation, making it suitable for environments where heat and sound conduction need to be controlled.

The production process of ceramic honeycomb

  1. Material preparation. High-quality ceramic powder is selected as the basic material, and a certain proportion of stabilizers, binders, and other auxiliary materials may be added according to specific needs to ensure that the ceramic honeycomb body produced has the required performance.
  2. Molding. Molding processes such as extrusion and injection molding are used to shape the material into a green body with a honeycomb structure.
  3. Sintering. Through the high-temperature sintering process, the formed body is turned into a dense and hard ceramic material, improving its high-temperature stability.
  4. Surface treatment. Depending on specific needs, ceramic honeycomb blocks are surface-coated or otherwise specially treated to enhance their specific properties.
