The objective of this study is to clarify the state of silver in a porcelain after firing and the increase mechanism of fracture toughness in the silver nano-particles doped porcelain. Porcelain disks including silver nano-particles up to 1 000ppm were fired and polished. Vickers hardness and the Median crack length developed were measured. Optical reflectance spectra were also recorded using a spectrophotometer in the wavelength range of 380-780 nm. In an increase in the fracture toughness of the silver nano-particles doped porcelain, it has been found that not only the contribution of silver ion but also dispersed silver nano-particle contributes.
