Product Details

⭐️ Product Description

Calcium Pyrophosphate (CPP) is an inorganic compound with the chemical formula Ca₂P₂O₇. It appears as a fine white to off-white powder, odorless, with excellent thermal stability and high purity. CPP is widely used in ceramics, coatings, food additives, pharmaceuticals, and specialty chemical applications due to its consistent quality and reliable performance.

📊 Chemical & Physical Properties

CPP is a stable and high-purity compound. It has a molecular weight of 222.11 g/mol, a slightly alkaline pH of 7–9 in 1% aqueous solution, and a bulk density of approximately 0.5–0.8 g/cm³. It is slightly soluble in water and insoluble in organic solvents. The particle size can be customized, ranging from 1 µm to 10 µm, according to specific application requirements. CPP is odorless and has a specific gravity of ~2.89.

📋 Specifications

Our Calcium Pyrophosphate products are offered in multiple grades tailored to industrial, food, and pharmaceutical needs. The typical properties include:

🔹 Assay (as Ca₂P₂O₇): ≥ 98%
🔹 Loss on Drying: ≤ 0.5%
🔹 pH (1% aq. solution): 7–9
🔹 Heavy Metals (as Pb): ≤ 10 ppm
🔹 Particle Size (D50): 3–7 µm
🔹 Residue on 45 µm sieve: ≤ 0.10%

Custom grades are available to meet specialized requirements for high-precision applications.

🛠 Applications

🌈 1. Ceramics & Glass Manufacturing
CPP acts as a melting aid and phase modifier, enhancing mechanical strength, controlling crystallization, and improving surface finish.

🌈 2. Coatings & Pigments
Used as a filler and dispersant, it provides scratch resistance, durability, and uniform coating distribution.

🌈 3. Food Additives
CPP functions as a leavening agent, anticaking agent, and calcium fortifier in powdered foods and baked goods. Local regulatory approval may be required for food-grade applications.

🌈 4. Pharmaceuticals & Nutraceuticals
It is used as a calcium supplement ingredient and for mineral-enriched formulations.

🌈 5. Specialty Chemicals
Serves as a precursor for advanced calcium phosphate materials and tailored inorganic composites.
