Porous Ceramic Ball

Product Detail

    summary

    KK porous ceramic ball is a new product developed on the basis of inert ceramic ball. It takes the diameter of the ball as the axis to make holes. It not only has certain mechanical strength, chemical stability and thermal stability as inert ceramic ball, but also increases the specific surface area and porosity, thus increasing the dispersion and flux of materials and reducing the resistance of the system. Since the product was put on the market, it has been widely used in the petroleum, chemical and natural gas industries to replace inert ceramic balls as the support and covering filler of catalyst, and has been well received by users.
