摘要

研究了添加二氧化硅（ATZS）的氧化铝增韧氧化锆（ATZS）以及用于制造牙冠的Aidite AiZir陶瓷的结构、相组成和力学性能。结果表明：制备的含硅量为2、3 mol %的ATZS陶瓷，其断裂韧性比Aidite AiZir高130%，抗压强度比Aidite AiZir高10%、4%，硬度比Aidite AiZir低14%、13%。ATZS陶瓷的高力学性能，以及其转化诱导塑性的能力和抗低温降解的能力，表明其作为替代进口牙科材料的良好前景。

Ratio of Compressive Strength to Fracture Toughness for Nanostructured Silicon-Containing ATZS Ceramics

The structure, phase composition, and mechanical properties of alumina toughened zirconia with a silica addition (ATZS), as well as Aidite AiZir ceramics, used to manufacture dental crowns, have been investigated. It is shown that the developed ATZS ceramics, containing 2 or 3 mol % silica, exceed Aidite AiZir by 130% in fracture toughness and by 10 and 4%, respectively, in compressive strength, while being inferior in hardness by 14 and 13%, respectively. The high mechanical properties of ATZS ceramics, as well as their ability to transformation-induced plasticity and increased resistance to low-temperature degradation, indicate good prospects of their use as an alternative import-substituting dental material.
