【 摘 要 】

The dental zirconia�?�leucite composites were synthesized by high temperature solid-state method using potash feldspar, potassium carbonate and zirconia as raw materials. The mechanical properties and the coefficient of thermal expansion (CTE) of the prepared zirconia�?�leucite composites were tested. The results show that the bending strength, the fracture toughness and the metal�?�ceramic bonding strength of the prepared samples are about 110 MPa, 3.5 MPa/m^1/2 and 45 MPa, respectively. The CTE was about 13.73�?10$^{-6} ^circ $C^-1 and close to that of Ni�?�Cr dental alloy (14.0�?10$^{-6} ^circ $C^-1). The results indicate that the introduction of zirconia is beneficial to the improvement in the mechanical properties and CTE adjustment of porcelain material. The clinical application of the zirconia�?�leucite composites with good metal�?�ceramic bonding strength in the dental restoration could be envisioned.
