Abstract: Examples of a crystal material and a preparation method are described. One example crystal material includes a secondary particle formed by agglomerating a plurality of monocrystalline grains. There are grain boundaries between the grains. Another example crystal material includes a monocrystalline particle. Each monocrystalline particle includes one monocrystalline grain. The crystal material is obtained by modifying a crystal material primary product in which monocrystalline particles have few defects, a gap at a grain boundary of a secondary particle is small, and bonding between grains is strong.
