The particle size of raw material on the ceramic proppants

In the sintering process of ceramics, the raw material of the finer particles, surface defects more lattice, more conducive to the increase of the sintering driving force.

  At the same time, a decrease in particle size can shorten the atomic migration and diffusion distance, accelerating the sintering process, thereby improving the compact degree of finished product structure, improving the performance of ceramic proppant.
