Sinterability of Calcium Phosphate Through Rapid Sintering

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 (...

Phosphate Recovery from Municipal Wastewater through Crystallization of Calcium Phosphate

Phosphate concentrations in municipal and agricultural wastewaters continuously increase because of the growing use of detergents and fertilizers. Thus, it seems that phosphate recovery from wastewater as calcium phosphate would be attractive due to the vast applications of calcium phosphate in industry. In the current experimental study, the phosphate recovery by addition of calcium chloride t...

Role of Amorphous Calcium Phosphate in Dentistry

  Objective: Amorphous calcium phosphate (ACP) is a reactive solution capable of releasing calcium and phosphate ions, conversion to apatite and remineralization of mineral tooth structure. This study reviews ACP structure, its properties and its applications in dentistry.   Methods: In this review study, keywords including “amorphous calcium phosphate”, “mineralization”, “hydroxyapatite”, “cas...

An improvement in sintering property of beta-tricalcium phosphate by addition of calcium pyrophosphate.

The sintering behavior of calcium pyrophosphate (CPP, Ca2P2O7)-doped beta-tricalcium phosphate [TCP, Ca3(PO4)2], prepared by solid state reaction, was investigated in-situ, using dilatometry. Pure beta-TCP undergoes phase transition to alpha-TCP at about 1200 degrees C; hence pure beta-TCP ceramics should be sintered bclow 1200 degrees C. Pure beta-TCP sintered body can achieve a relative densi...
