Flexible Preparation Methods:Can be produced by both solid-state reaction and aqueous precipitation, allowing adaptable manufacturing processes for different application needs.
Controllable Crystal Phases:Exhibits distinct α and β crystal forms at different temperatures, enabling phase control for specific performance requirements.
Stable Chemical Properties:Insoluble in water but soluble in dilute acids, providing good stability during storage and reliable behavior in various formulations.
Thermal Decomposition Capability:Decomposes at high temperature into useful phosphate compounds, making it suitable as a precursor in high-temperature and chemical processing applications.
Product Description
Product Description of CALCIUM PYROPHOSPHATE CAS#7790-76-3
Calcium Pyrophosphate (Ca₂P₂O₇, MW 254.14 g/mol) is prepared by heating dibasic orthophosphate or reacting soluble calcium salt with pyrophosphoric acid. The solid-state route yields amorphous product at 240–500 °C; higher temperatures generate distinct crystal phases: β-phase over 750 °C and α-phase at 1140–1350 °C. The aqueous method obtains its dihydrate Ca₂P₂O₇·2H₂O, a water-insoluble white powder soluble in dilute acids. Anhydrous calcium pyrophosphate decomposes into metaphosphate and calcium oxide at 1353 °C. It is dimorphic, and the high-temperature α-phase transforms back to β-phase around 950 °C upon reheating.
Product Application of CALCIUM PYROPHOSPHATE CAS#7790-76-3
Calcium Pyrophosphate is used in phosphoric acid and fertilizer production. It acts as an acidic ingredient in baking leavening systems and is also applied in processed cheese. Moreover, it finds applications in cell gene transfection and the development of contrast agents.

FAQ
Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.
Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.
Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.
Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
