Fabrication of β-TCP foam: Effects of magnesium oxide as phase stabilizer on its properties

Porous β-tricalcium phosphate (β-TCP) has attracted attention as an artificial bone substitute. α-TCP foam that mimics the fully interconnected porous structure of the cancellous bone can be fabricated by a ceramics foam method, which requires sintering at high temperature. However, β-TCP foam could not be fabricated by the ceramics foam method since the sintering temperature required is above the αβ transition temperature. To fabricate the...
