FORMULA CaCO₃

SUMMARY OF TDS-OA-001

REV C · OCT 2026

Description

Oolitic aragonite is a naturally occurring polymorph of calcium carbonate formed in warm, shallow Bahamian marine conditions. Its orthorhombic crystal structure differs from calcite and can affect dissolution and process behavior. The described preparation includes mechanical collection, washing, screening, drying and classification without quarry blasting or a calcination step.

Applications

Supplied as four grades — AG-CAL for agriculture, horticulture, turf and feed; GL-CAL for glass batch; WT-CAL for water treatment, aquaculture and remediation media; PL-CAL for polymers and coatings — and as a custom classification to a written specification for oilfield, construction and other application-specific programs.

Custom classification is offered across 20–325 U.S. mesh to a written specification for applications the four grades do not cover. Full composition (15 constituents), physical properties and the screen specification are in TDS-OA-001; each grade sheet carries the values that apply to it.

Packaging

Available configurations are confirmed by grade, volume, destination and current quotation.

Handling & storage

Store dry and covered. Avoid dust generation and follow the SDS for exposure controls and PPE.

Documentation

TDS-OA-001 and one technical data sheet per grade are published. The safety data sheet and the third-party laboratory report are supplied on request, and a certificate of analysis is issued for each dispatched lot.
