HIGH-PURITY GEOTHERMAL FOUNDATION
CALCIUM CARBONATE
A naturally reprecipitated geothermal calcium carbonate sourced and processed in the United States. Thermocal® delivers consistent composition and fine, uniform particle profiles designed to support livestock nutrition and environmental pH management applications.
Thermocal Calcium Carbonate Variations
Thermocal® Flake
A coarse, structurally stable calcium carbonate designed to provide sustained reactivity in feed applications. The flake format supports gradual dissolution and consistent calcium availability in livestock rations.
Thermocal® Neutralizer
A fine, uniform calcium carbonate designed for rapid environmental interaction and pH stabilization. The Neutralizer grade is ideal for livestock bedding, moisture management, and environmental buffering applications.

The Thermocal Difference
Thermocal® is derived from geothermally reprecipitated calcium carbonate sourced from a single, traceable U.S. deposit. This controlled origin, combined with refined milling and third-party testing, supports consistent composition and predictable performance in livestock and environmental applications.
