Why is a lightweight ceramic proppant not simply called a low-strength or low-density proppant? This article explains the naming logic and the performance metrics buyers should evaluate, including apparent density, bulk density, crush resistance, and conductivity.

This article explains how cenospheres form in coal fly ash, how their hollow spherical structure differs from ordinary fly ash, and how they are recovered for use in lightweight fillers, coatings, insulation materials, and oil-well cementing applications.

Carbon and sulfur analysis helps verify the chemical composition of high-carbon cast-steel grit and shot. This article explains representative batch sampling, high-frequency infrared testing, why carbon and sulfur matter, and how to review the analyzer's measurement curves. It also references the composition requirements of ISO 11124-3:2018.

Before placing a first full-container order for calcined bauxite, buyers should confirm the target specifications and testing criteria. This article covers sample requests, technical documents, sample evaluation, and the delivery details to agree on before bulk purchasing.

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.

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.
