Chemical Properties of Aluminum-containing Tricalcium Phosphate

Chemical stability of grain boundaries in β-tricalcium phosphate ceramics

tricalcium phosphate containing sodium hexametaphosphate as polymer suspension stabilizer

tricalcium phosphate as hydroxyapatite is used as a suspension stabilizer in styrene polymerization process. particle size of tcp plays an essential role in the particles’ size distribution and geometrical form of polystyrene products. as the particle size of tcp is reduced, there will be much better chance to engulf the styrene particles. the higher the number of tcp particles surrounding each...

Difference in Osteoclast Responses to Tricalcium Phosphate in Culture Medium Supplemented with Zinc and to Zinc-Containing Tricalcium Phosphate

Difference in osteoclast responses (i.e., apoptosis, actin ring formation) to tricalcium phosphate (TCP) in culture medium supplemented with zinc and to zinc-containing tricalcium phosphate (ZnTCP) was investigated in this study. On the TCP ceramic, an increase in zinc ion in the culture medium within the range between 0.3 and 6.8 ppm significantly induced an increase in osteoclast apoptosis an...

CALCIUM PHOSPHATE CEMENT: STUDY OF (BETA-TRICALCIUM PHOSPHATE, DICALCIUM PHOSPHATE AND CALCIUM CARBONATE SYSTEM

Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca3 (P04)2), dicalcium phosphate (DCP, CaHP04), calcium carbonate (Ca CO3), and hydroxylapatite (HAp, Ca10(P04)6(OH)2) as powder cement and disodium hydrogen phosphate (Na2HP04) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (...

The role of the chemical composition of monetite on the synthesis and properties of α-tricalcium phosphate.

There has been a resurgence of interest in alpha-tricalcium phosphate (α-TCP), with use in cements, polymer composites and in bi- and tri-phasic calcium phosphate bone grafts. The simplest and most established method for preparing α-TCP is the solid state reaction of monetite (CaHPO4) and calcium carbonate at high temperatures, followed by quenching. In this study, the effect of the chemical co...
