Diatomite Sold Or Used, By Major Use

This table presents data on the quantities of diatomite sold or used in the United States, categorized by its primary applications. Diatomite is a naturally occurring, soft, siliceous sedimentary rock with a variety of industrial uses, most notably in filtration processes. Tracking the volume of diatomite consumed in different sectors provides valuable insight into industrial demand patterns and economic activity related to manufacturing, environmental management, and construction. This information is critical for stakeholders including producers, policymakers, and researchers to understand market trends, allocate resources efficiently, and anticipate shifts in industrial needs.

The data reveals a notable decline in diatomite usage for filtration, dropping from 563 thousand metric tons in 2023 to 433 thousand metric tons in 2024, a decrease of approximately 23%. This reduction significantly impacts the overall total, which fell from 849 to 721 thousand metric tons during the same period. Conversely, the category labeled "Other," which encompasses abrasives, absorbents, cement, fillers, insulation, and unspecified uses, remained relatively stable, increasing slightly from 286 to 288 thousand metric tons. The sharp decrease in filtration use suggests either a shift in filtration technologies, changes in demand within industries relying on diatomite for filtration, or possible supply constraints. Meanwhile, the steadiness in other uses indicates sustained industrial reliance on diatomite for diverse applications beyond filtration.
