Product Overview
LIFETECH® grades are lithium carbonate-based accelerating admixtures that contain no sodium or potassium alkalis.

LIFETECH® Ultrafines is the finest of all available lithium carbonate grades from Livent. It offers excellent control, uniformity, and a predictable rate of reaction in a variety of industrial applications.

LIFETECH® lithium carbonates provide the fine particle size and narrow size distribution for applications where reactivity and performance are based on the surface area of the lithium carbonate particles.
