| Abstract Scope |
The effect of calcium hexaaluminate and boric acid doping on commercially available dental powder was investigated. The ceramic samples were produced using the dental powder and dopants to detect the improvements in durability of ceramic teeth. The samples were prepared homogenously prior to sintering to avoid the porosity in the ceramic. Three different test groups were sintered to determine the effect doping with different proportions of boric acid, calcium hexaaluminate and both. The characterizations of the sintered products in different temperatures were conducted by firing shrinkage, micro hardness, thermal shock, colorimetric, SEM and XRD tests. Moreover, water adsorption and three point flexure tests were performed on the samples. The experimental results were evaluated with regard to durability and whitening of the ceramic teeth. The optimum proportions of boric acid (2%) and calcium hexaaluminate (3%) were determined with sintering temperatures between 800 and 950°C. |
