Transparent glass-ceramic composite micro-bead material and preparation method thereof
The invention provides a transparent glass-ceramic composite micro-bead material and a preparation method thereof. The transparent glass-ceramic composite micro-bead material includes an inner core and an outer shell and is characterized in that the inner core is glass micro-beads, and the outer shell is made of a ceramic material; the particle diameter of the glass micro-beads is 10-20 microns; the ceramic material is composed of the components according to the mole ratio: 1-2 of ZrO2, 0.1-0.2 of SiO2, 0.2-0.4 of Al2O3, 0.05-0.1 of MgO, and 0.02-0.15 of Y2O3; and the particle diameter of the transparent glass-ceramic composite micro-bead material is 25-45 microns. The transparent glass-ceramic composite micro-bead material has the hardness, crushing resistance, abrasion resistance and sphericity all greater than those of the glass micro-beads having the same particle diameter, and has the refractive index of about 1.9-2.2.
