Porcelain balls, as an important industrial material, are widely used in petroleum, chemical, fertiliser, natural gas and environmental protection industries. Its manufacturing process and material properties are the key factors that determine the quality of porcelain ball.

The key process of manufacturing porcelain ball includes raw material selection, moulding, firing and grinding. First of all, the selection of raw materials is the basis, directly related to the chemical stability and mechanical properties of the ball. Generally speaking, the main raw materials of porcelain ball are kaolin, china stone, etc. These raw materials must be pure and have few impurities to ensure the performance of porcelain ball. Secondly, the moulding process is to make the raw materials into a certain shape of the embryo by pressing or rolling. In this process, the pressure and humidity should be strictly controlled to prevent the embryo from cracking or deformation. Once again, the firing process is to fire the moulded embryo body at high temperature to make the embryo body porcelain. In this process, the temperature and firing time are very critical, and they determine the physical properties and appearance of the porcelain balls. Finally, the grinding process is to grind and polish the fired porcelain balls to achieve the required surface finish.

The material properties of porcelain balls are mainly reflected in their chemical stability, mechanical properties and thermal stability. As the ball in many occasions will come into contact with acid, alkali and other corrosive substances, therefore, it must have excellent chemical stability, can maintain stable performance in a variety of chemical environments. Mechanical properties, porcelain ball needs to have a certain degree of pressure, impact and wear resistance. This is because the porcelain ball in the process of transport and use, may be subjected to external forces, if the mechanical properties are not good, it is easy to damage. Thermal stability is also an important characteristic of porcelain ball. In a high temperature environment, the porcelain ball can not appear deformation, cracking and other phenomena, which is related to the service life and safety of the porcelain ball.

In addition, the water absorption rate of porcelain ball is also an important parameter. High-quality porcelain ball should have a low water absorption rate, which means that the performance of porcelain ball in the humid environment will be slower decay. The appearance quality of the ball is related to its aesthetics and usage experience, so it also needs to be given enough attention.
