This invention discloses a dry ice crystal particle, its preparation method, and a ceramic tile, relating to the field of ceramic tile technology. The dry ice crystal particle is prepared from a first flashing frit, a second flashing frit, and a matte frit. Since the dry ice crystal particle is composed of three frits with different refractive indices and firing temperatures, different phases can be formed due to the different firing temperatures of each frit. The differences in light transmittance and refractive index between these phases are then utilized to create a better flashing effect. Simultaneously, the matte glaze serves as a backdrop, further enhancing the display of the flashing effect.
