Introductio
Rare Earth Ceramic Sand is also popularly known as ceramic sand, which is a kind of grayish-white ball in appearance. It is made of porcelain mud, clay, rare earth, and other materials as raw materials, mixed with appropriate pore-forming agents and binders, and sintered through multiple processing and production processes. Its particles are uniform, hard, wear-resistant, and high-temperature resistant, and chemical stability is good, so it has a wide range of applications. At the same time, its high porosity and strong ability to absorb impurities make it widely used in sewage treatment of various industries. In addition, it is very popular because it can solve the problems of the single proportion of natural filter material, easy to break, and secondary pollution.
