Zirconia materials are primarily composed of zirconia crystals and doped with other elements. Based on their crystal structure, common zirconia materials can be divided into three categories:
1. Monoclinic Zirconia (m-ZrO2): This type of zirconia has a loose crystal structure, a high specific surface area, and good hydrolysis and phase transformation capabilities at room temperature. Due to its poor high-temperature resistance, it is generally used to prepare alumina, perovskite, and other ceramic materials.
2. Tetragonal Zirconia (t-ZrO2): This type of zirconia has a high phase transformation temperature, resulting in high high-temperature resistance and chemical stability. It is commonly used in high-temperature structural materials, cutting tool materials, and materials with special properties such as conductivity and magnetism.
3. Cubic Zirconia (c-ZrO2): This type of zirconia does not exhibit a strong solid solution effect, possesses good chemical inertness and high mechanical properties, and is widely used in diamond synthesis, high-efficiency grinding, and other fields.
