Applications

Barium sulfate is formulated into oral or rectal suspensions that are radiopaque but not systemically absorbed, used to visualize the GI tract under X-ray/CT.

Calcium carbonate serves as a bulk diluent and talc as a glidant/lubricant, ensuring uniform tablet weight and smooth compression.

High-purity calcium carbonate acts as the active ingredient itself, neutralizing stomach acid or supplementing dietary calcium.

Talc's fine particle size and absorbency make it a base ingredient in medicated dusting powders and dermatological formulations.

Calcium carbonate and talc are pre-blended as diluent and anti-caking/flow aids during wet or dry granulation of drug formulations.

Filler / active ingredient
Functions as a tablet filler/diluent in most formulations, and as the active antacid or calcium-supplement ingredient at pharmaceutical-grade purity.
