Overview
Calcium phosphate is a versatile inorganic compound with the chemical formula Ca3(PO4)2. It is commonly found in nature as the mineral apatite and is a major component of bones and teeth. Due to its biocompatibility and stability, it is widely used in various industrial and medical applications. In the food industry, calcium phosphate serves as an anti-caking agent, nutritional supplement, and leavening agent. It is also a key ingredient in fertilizers, providing essential phosphorus and calcium to plants. In dentistry and medicine, it is used in bone grafts and dental cements.
Physical and Chemical Properties
Calcium phosphate is a white, odorless powder or crystalline solid with a density of 3.14 g/cm³. It is insoluble in water but dissolves in acids, making it useful in various chemical processes. The compound has a high melting point of 1670°C, at which it decomposes rather than boiling. Its stability and non-toxic nature make it suitable for applications requiring biocompatibility, such as medical implants and food additives. The compound's insolubility in water ensures it remains stable in most environmental conditions, though it should be stored away from strong acids to prevent decomposition.
Main Applications
Calcium phosphate's primary use is as a food additive, where it acts as a calcium supplement, anti-caking agent, and pH regulator. It is commonly found in baked goods, dairy products, and nutritional supplements. In agriculture, calcium phosphate is a key component of phosphate fertilizers, providing essential nutrients for plant growth. The compound is also used in dental materials, such as toothpaste and bone grafts, due to its biocompatibility and resemblance to natural bone minerals. Additionally, it serves as a raw material in the production of phosphoric acid and other phosphorus-containing chemicals.
Safety and Storage
Calcium phosphate is generally considered safe for use in food and medical applications. However, prolonged exposure to dust should be avoided, as inhalation may cause respiratory irritation. Proper personal protective equipment, such as masks and gloves, is recommended when handling large quantities. The compound should be stored in a cool, dry place, away from incompatible substances like strong acids. Containers should be tightly sealed to prevent moisture absorption and contamination. Shelf life is typically long if stored under appropriate conditions.
B2B Procurement Guide
When procuring calcium phosphate for industrial use, buyers should verify the CAS number (7758-87-4) to ensure product authenticity. Purity levels, typically ranging from 95% to 99%, should be confirmed based on application requirements. Suppliers should provide certificates of analysis (CoA) and comply with relevant industry standards, such as food-grade or pharmaceutical-grade specifications. Bulk pricing varies depending on quantity and purity, with reference prices ranging from $500 to $1000 per metric ton. Buyers are advised to sample test batches before large-scale purchases.
