This guide presents the specifications and key performance indicators of SEPPE SEPLITE LWP, SEPROP ISP and SEPREM HSP ceramic proppants. It compares mesh sizes, apparent density, bulk density and crush resistance, and explains particle size distribution, roundness, sphericity, acid solubility, turbidity and conductivity for proppant selection.

Refractory-grade calcined bauxite cannot be selected by alumina content alone. This guide explains commercial grades, critical COA values and batch qualification.

SEPPE tests cenospheres for flotation rate, loose bulk density, particle density, morphology, and particle size distribution. This article explains the testing methods used for CenoLite oil-well cementing and coating grades, with laboratory photos, particle size charts, and technical data sheets.

This article compares dry powder cenospheres, wet-state cenospheres and cenosphere slurries in terms of applications, transportation, storage, feeding and dispersion. It also introduces SEPPE dry-powder grades for oil-well cementing and coating applications, together with key quality-control parameters including flotation rate, density, particle size, moisture content, chemical composition, compressive strength and dispersion performance.

Learn how to evaluate ceramic proppant quality through crush ratio, sphericity, roundness, particle size distribution, acid solubility and turbidity. The article also includes SEPPE LWP, ISP and HSP density ranges, available sizes, crush-test data and TDS links for technical comparison and grade selection.

This article explains how ceramic proppant is produced from selected bauxite and mineral additives. It follows the main production stages—crushing, dosing, grinding, pelletizing, sintering, cooling and screening—and introduces the process controls, final testing and packaging required for consistent product quality.

Ceramic proppants are normally quoted by metric ton, but differences in bulk density mean LWP, ISP and HSP require different weights for the same volume. This article explains how to convert USD/MT into cost per cubic meter and why closure stress, placement and pumping requirements must guide the final grade selection.

Calcined bauxite powder in 200- and 325-mesh sizes helps improve particle packing, sintering efficiency and slurry uniformity in refractory, precision-casting and coating formulations. This article also explains how dry, sealed storage helps prevent moisture absorption, caking and contamination.

SEPPE calcined bauxite is widely used as a high-performance aggregate for high friction surfacing (HFS), anti-skid roads and safety flooring. Its high hardness, low abrasion loss and resistance to polishing help maintain long-term surface friction in demanding traffic environments.

How calcined bauxite is made matters more than its alumina content. Small variations in processing can lead to unstable density and shorter refractory life. That's why SEPPE uses rotary kiln processing for consistent batch stability and reliable performance.
