Runhuabang white and yellow diatomite powder for building materials plastic materials water purification soil improvement

Diatomite powder, a fine, porous material, originates from the fossilized remains of diatoms—microscopic algae with silica-based cell walls. These organisms thrive in aquatic environments like oceans, lakes, and rivers. Over millions of years, their skeletal remains accumulate on water beds, forming sedimentary deposits.

The process begins with mining diatomite ore, typically from ancient lakebeds or marine sediments. The raw ore is crushed and heated to remove organic matter, a process called calcination, which enhances its porosity and whiteness. Further milling and air classification refine the powder into various grades, ranging from coarse to ultra-fine particles.
