Tricalcium phosphate (TCP) is a calcium salt of phosphoric acid with the chemical formula Ca₃(PO₄)₂.It is a white, odorless powder with various applications in the food industry, pharmaceuticals, and as a nutritional supplement.Here is an introduction to the basic properties of tricalcium phosphate:
Chemical Composition:
Formula: Ca₃(PO₄)₂
Molecular Weight: Approximately 310.18 g/mol
Physical Appearance:
White, odorless powder or crystalline solid.
Insoluble in water.
Calcium Content:
Tricalcium phosphate is a significant source of calcium, an essential mineral for the human body.It provides bioavailable calcium, which is important for bone and teeth health.
Phosphorus Content:
As a phosphate compound, tricalcium phosphate contains phosphorus, another essential nutrient necessary for various physiological functions, including energy metabolism and bone formation.
Crystalline Forms:
Tricalcium phosphate exists in different crystalline forms, with the most common being aβ-Ca₃(PO₄)₂and a high-temperature form, α-Ca₃(PO₄)₂.
Biocompatibility:
Tricalcium phosphate is known for its biocompatibility, making it suitable for use in medical and dental applications, particularly as a bone substitute material in orthopedic and dental surgeries.
