Introduction: Porous ceramics are ceramic materials with fine pore structure. They are widely used in various fields due to their high porosity, high air permeability, high thermal stability and high mechanical strength. Among them, vacuum suction cups are an important application direction of porous ceramics. This article will introduce in detail the application of hole-like ceramics in vacuum suction cups, including materials, manufacturing processes, application fields, and development trends.

Porous ceramic materials include alumina and silicon carbide, which have excellent physical and chemical properties and can maintain stable performance in harsh environments such as high temperature, high pressure, and corrosion.

Porous ceramic materials have the following performance characteristics:

1. High specific surface area: porous ceramic materials have a high specific surface area, which is beneficial to adsorbing gas molecules and improving the adsorption performance of the vacuum suction cup.
2. High temperature resistance: porous ceramic materials have a high melting point and can maintain stable performance in high temperature environments.
3. Corrosion resistance: porous ceramic materials have good chemical stability and can resist erosion by various corrosive media.
4. Wear resistance: porous ceramic materials have higher hardness and better wear resistance.
