Effect of Sintering Temperature on the Diametral Tensile Strength of β-Tricalcium Phosphate Block

Abstract:

The effect of sintering temperature on the diametral tensile strength of β-tricalcium phosphate (β-TCP) block was investigated. Uniaxially pressed block of mixture of calcium hydrogen phosphate dihydrates (CaHPO₄2H₂O) and calcium carbonate (CaCO₃) were pressed at 5 MPa and sintered at 1000°C, 1050°C and 1100°C. XRD analysis revealed that single phase β-TCP was obtained at all sintering temperature. The porosity obtained from β-TCP block sintered at 1100°C was found to be lower than that sintered at 1000°C and 1050°C. Diametral tensile strength (DTS) value of β-TCP block sintered at 1100°C showed significantly higher value than β-TCP block sintered at lower temperature. It is therefore concluded that the increased in sintering temperature affects the mechanical strength of the β-TCP block.
