Preparation and mechanical properties of β-tricalcium phosphate ceramics doped vanadate ion

Abstract

β-tricalcium phosphate (β-TCP) doped with various amounts of vanadate ions (VO-TCP) was prepared via solid state reaction, and the mechanical properties of sintered VO-TCP were investigated. The prepared sample consisted of single β-TCP phase up to 2.5 mol%, and V₂O₅ as impurities formed above 2.5 mol%. The a- and c-axis constants decreased slightly and increased linearly up to 0.50 and 2.5 mol%, respectively, and then remained the same value. The bending strength of sintered VO-TCP was increased with an increase in the amount of vanadate ions because of the increase in sinterability.
