1. Toughened zirconia beads refer to adding a certain amount of precious metal elements, such as zirconium, to alumina, thereby increasing the incompleteness of the crystal lattice and the energy of the crystal interface, allowing more crystals to be formed under the action of external forces. boundaries, and absorb the energy required for crack expansion through the grain boundaries, thus playing a toughening role. Yttrium-stabilized zirconia beads refer to adding a certain amount of yttrium (Y) element into the zirconia lattice to form a solid solution, thereby stabilizing the structure of the zirconia crystal and improving its chemical stability and heat resistance.
2. Due to the increase in grain boundaries and energy absorption, toughened zirconia beads have better resistance to penetration, fatigue and fracture resistance, and are especially suitable for grinding and grinding under special processing conditions such as high speed, high load and strong impact. Grinding; while yttrium-stabilized zirconia beads have better stability and corrosion resistance at high temperatures, and are suitable for dielectrics, chemical valves, zirconia microwave heaters and other fields under high temperature conditions.
