Introduction to porous ceramics

Porous ceramic materials with vary according to the pore size. for ultramicropore ceramics and extremely small pores, the pore size is several times of the molecular diameter. During adsorption, the pore wall surrounds the adsorption molecules, and the adsorption force in the pore is very strong. for medium hole and large hole, the pore size is more than 10 times larger than the diameter of adsorbed molecules, and typical capillary condensation occurs. according to the shape of the hole, sometimes there will be a series of phenomena such as adsorption hysteresis.

In order to correctly analyze the pore size of the material, it is necessary to have a clear understanding of the pore structure of the material, select the correct pretreatment method (temperature, atmosphere, vacuum degree) and the appropriate analysis model, so as to obtain accurate and scientific experimental results. Fountyl Technologies PTE Ltd's porous ceramic materials have many excellent physical and chemical properties due to their special structure, such as high specific surface area, high porosity, high adsorption...etc. Therefore, they are widely used in semiconductor, chemical industry, environmental protection, functional materials fields. Gas adsorption method is one of the most important methods to characterize the pore structure of porous materials. Fountyl's team has been deeply engaged in the field of microporous ceramic adsorption for more than ten years, and has done detailed market research and analysis in semiconductor, chemical, environmental protection, functional materials fields, understanding the user's pain points and industry problems. Faced with the shortcomings of current vacuum chuck application technology, Fountyl has a perfect solution to settle.

Application principle of porous ceramic vacuum chuck: Set the negative vacuum pressure of the air into the Fountyl porous ceramic, can adsorb the workpiece. The vacuum positive pressure air flow is set to flow out of the ceramic, and the parts may be blown up or not touched with the ceramic.

Porous ceramics themselves have many holes through ceramic sintering technology and can be used in vacuum chuck. It can be used as an air flotation platform and is widely used in semiconductors, panels, laser processes and non-contact linear sliders. By applying positive and negative pressure, gas absorbs or floats the workpieces, workpieces including wafers, glass, PET films or other thin objects.
