最后指出晶体硬度不仅与晶体的结构、晶格能有关，而且也与温度的影响有关。
These results indicate that the microhardness of crystals depends not only on the crystal structure and lattice energy but also on temperature.
与棕，白刚玉相比硬度高，韧性大，呈单颗粒球状晶体，具有良好的多棱切削刃，抗破碎较强。
With brown, white fused alumina compared to high hardness, toughness, showed a single particle spherical crystal, has a good multi-row cutting edge, strong anti-crushing.
