Shale ceramic particles

Shale ceramic particles are lightweight, high-strength aggregates produced by firing shale at high temperatures (typically 1100°C to 1300°C). The process causes the shale to expand, forming a porous, honeycomb-like internal structure while maintaining a hard, vitrified outer shell. These particles are widely used in the oil and gas industry as proppants for hydraulic fracturing, in construction as lightweight concrete aggregates, and in horticulture as soil conditioners. The global demand for shale ceramic particles has grown steadily due to their superior crush resistance, thermal stability, and low density compared to natural sand or bauxite-based proppants.

Key properties include a specific gravity ranging from 2.0 to 2.8 g/cm³, bulk density between 0.8 and 1.5 g/cm³, and a particle size distribution from 0.1 mm to 5 mm. These characteristics make them ideal for applications requiring high permeability and mechanical strength under extreme subsurface conditions.
