Description

Calcium Phosphate Gel (Aged) is a specialized, high-purity inorganic compound widely recognized for its unique rheological and adsorptive properties. This product is essential for applications requiring a stable, finely-dispersed colloidal system with a high surface area. It is particularly valued in the pharmaceutical and biotechnology sectors for its efficacy as an excipient and an active agent. Industries such as nutraceuticals, advanced ceramics, and catalysis also rely on its consistent quality and performance.

Application

• Pharmaceutical Excipient: Used as a suspending, thickening, or gelling agent in oral and topical formulations.
• Antacid & Phosphate Binder: Acts as an active pharmaceutical ingredient (API) in medications for hyperphosphatemia and gastric acid control.
• Biomaterial & Bone Graft Substitute: Serves as a biocompatible scaffold in dental and orthopedic applications due to its similarity to natural bone mineral.
• Nutraceutical Carrier: Functions as a carrier for calcium and phosphate in dietary supplements and fortified foods.
• Catalyst Support: Provides a high-surface-area substrate for various heterogeneous catalysts in chemical synthesis.
• Chromatography Media: Utilized in the purification of biomolecules, including proteins and nucleic acids.
• Ceramic Precursor: Acts as a starting material for producing high-purity calcium phosphate ceramics.
• Research & Development: Employed in laboratory studies for adsorption, material science, and biomedical research.

Quality Control

Our Calcium Phosphate Gel (Aged) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and performance. We can supply material compliant with relevant pharmacopeial standards (e.g., USP/NF, Ph. Eur.) for pharmaceutical applications, as well as Food Chemical Codex (FCC) grade for nutritional use. A comprehensive Certificate of Analysis (COA) documenting all critical quality attributes is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a cool, dry place to prevent changes in consistency and properties. Do not freeze.
