Tri-Calcium Phosphate (TCP)
Introduction to Tricalcium Phosphate
Tricalcium Phosphate (TCP) is an essential compound widely used in various industries, including food, pharmaceuticals, agriculture, and ceramics. Chemically represented as Ca3(PO4)2, it is a calcium salt of phosphoric acid and plays a crucial role as a calcium supplement, food additive, and industrial ingredient.
As a leading manufacturer, supplier, dealer, and wholesaler, HTMC Group provides high-quality Tricalcium Phosphate that meets industry standards. With years of expertise and state-of-the-art facilities, we ensure top-notch production and distribution of TCP to various sectors worldwide.
How Tricalcium Phosphate is Processed
HTMC Group follows a meticulous manufacturing process to ensure high purity and quality in every batch of Tricalcium Phosphate. The production process includes:
1. Raw Material Selection
We source high-grade calcium carbonate and phosphoric acid as the primary raw materials to ensure the highest quality standards.
2. Precipitation Reaction
- Calcium carbonate (CaCO3) is reacted with phosphoric acid (H3PO4) under controlled conditions.
- The chemical reaction leads to the precipitation of Tricalcium Phosphate in a crystalline form.
- The precipitated Tricalcium Phosphate is separated through filtration.
- It is then washed multiple times to remove any impurities or residual acids.
- The filtered material is dried at optimal temperatures to ensure stability.
- It is then ground into a fine powder to meet industry requirements.
- Our quality control team conducts rigorous testing to ensure compliance with industry and safety standards.
- The final product is securely packaged in moisture-resistant bags to maintain purity and extend shelf life.

Properties of Tri-Calcium Phosphate
- Molecular Formula Ca₃(PO₄)₂
- Molar Mass 310.18 g/mol
- Solubility Insoluble in water but soluble in acids.
- Melting Point Approximately 1670°C.
- Appearance White powder with an odorless, tasteless nature.
- Bioactivity TCP is biocompatible and bioactive, meaning it can interact with biological systems without causing harmful reactions, making it useful in medical implants and bone grafts.
Types of Tri-Calcium Phosphate
- Alpha-TCP (α-TCP): This type consists of more than 90% calcium oxide (CaO). It is the most common form used in various industrial applications due to its high reactivity and purity.
- Beta-TCP (β-TCP): This form is more stable and has a slower resorption rate compared to alpha-TCP. It is commonly used in long-term orthopedic applications, as it provides a gradual release of calcium and phosphate ions, which help in bone regeneration.
- Amorphous TCP (ATCP): While technically not quick lime, hydrated lime (Ca(OH)₂) is produced by reacting quick lime with water. It has a specific range of applications, especially in water treatment and construction.
Uses and Applications of Tri-Calcium Phosphate
- Food Industry TCP is used as a food additive, functioning as an anti-caking agent, nutritional supplement, and stabilizer. It’s often found in powdered products like milk powder, baking powders, and processed foods. It’s also used to fortify foods with calcium.
- Pharmaceuticals: In the pharmaceutical industry, TCP is used as a calcium supplement in tablets and capsules. It acts as a diluent in the preparation of various medications, ensuring consistency in dosage.
- Biomedical Applications: Due to its biocompatibility, TCP is widely used in orthopedics and dentistry. It serves as a scaffold for bone regeneration and as a material in dental implants. TCP is gradually absorbed by the body, promoting natural bone growth as it dissolves.
- Cosmetics: TCP is used as an abrasive and bulking agent in some cosmetic products. It adds texture to formulations and can assist in the delivery of other ingredients.
- Animal Feed:TCP is an important ingredient in animal feed, serving as a calcium and phosphorus source for poultry, cattle, and other livestock.
Applications in Detail
- Bone Grafts and Implants TCP is used in orthopedic and dental surgeries as a synthetic bone graft material. It supports bone growth by providing a scaffold for new bone formation. Both α-TCP and β-TCP are resorbable materials that dissolve over time, reducing the need for additional surgeries to remove implants.
- Calcium Fortification In the food industry, TCP is added to products like milk, juices, and cereals to increase calcium content, contributing to better bone health in consumers.
- Pharmaceutical Tablets In the pharmaceutical sector, TCP acts as an excipient, facilitating the manufacturing of tablets. It ensures the right texture and stability of the product while providing calcium as an active ingredient in supplements.
