Definition

Noun A compound of calcium and phosphorus, specifically a salt of phosphoric acid containing calcium ions. It is the primary inorganic component of vertebrate bones and teeth, providing rigidity and strength.

Usage

Calcium phosphate is used as a precise chemical term to refer to the mineral family that forms the hard structure of bones and teeth. It is also used in contexts like nutrition, medicine, and materials science. - Primary Usage: Referring to the bone mineral. - Secondary Usage: Referring to compounds used in food additives, fertilizers, or supplements.

Examples
  • In Biology/Medicine:
    • Hydroxyapatite, a crystalline form of calcium phosphate, is what makes bones hard.
    • A deficiency in calcium phosphate can lead to weakened bones.
  • In Industry/Chemistry:
    • Tricalcium phosphate is a common food additive used as an anti-caking agent.
    • The laboratory synthesized a new type of calcium phosphate for ceramic implants.
Advanced Usage
  • "Calcium phosphate deposition": The process by which this compound forms solid deposits, crucial in bone formation and sometimes in pathological conditions like kidney stones.
    • The study focused on the mechanisms of calcium phosphate deposition in developing bone tissue.
  • "Calcium phosphate cement": A bioactive material used in orthopedic and dental surgeries to repair bone defects.
    • The surgeon used a calcium phosphate cement to fill the cavity in the patient's skull.
