Overview
The pharmaceutical industry requires mineral excipients of the highest purity and traceability. Raviraj Minerals supplies pharmaceutical-grade calcium carbonate and talc that comply with international pharmacopoeia standards for use as excipients, antacids, calcium supplements, tablet glidants, and coating aids.
Calcium Carbonate
Pharmaceutical-grade calcium carbonate from Raviraj Minerals is used as a primary excipient and active pharmaceutical ingredient (API). As an antacid, it neutralizes excess stomach acid for immediate relief. As a calcium supplement, it provides bioavailable elemental calcium in tablet and chewable forms.
Our pharma-grade CaCO₃ is manufactured under strict GMP conditions, tested for heavy metals, arsenic, lead, microbiological limits, and particle size distribution to meet BP, USP, and IP pharmacopoeia specifications.
- Used as an antacid API in direct-compression tablet formulations
- Calcium supplement in tablets, chewables, and nutraceutical products
- Acts as a tablet diluent and binder in multi-component tablet formulations
- High bioavailability of calcium with low heavy metal content
- Complies with BP/USP/IP pharmacopoeia specifications
Talc Powder
Pharmaceutical-grade talc is used as a glidant, lubricant, and anti-adherent in tablet manufacturing. Raviraj Minerals supplies talc tested for fibre content (asbestos-free), heavy metals, and microbial contamination to meet the highest pharmaceutical standards.
- Glidant — improves powder flow in tablet compression machines
- Lubricant — reduces friction between tablet and die during ejection
- Anti-adherent — prevents sticking of tablet mass to punches and dies
- Used in tablet coating formulations for moisture barrier and opacity
- Asbestos-free and tested to IP/BP/USP standards
