A customer representative witnessed the pre-shipment inspection of a SEPPE steel shot and grit export order. The inspection covered batch sampling, package weight checks, particle-size distribution, hardness, metallographic structure, container condition and loading.

Brown Fused Alumina ( BFA ), also called Brown Fused Aluminium Oxide, Brown Aluminum Oxide or Brown Corundum,named by its mainly brown color, is an artificial electric fused corundum obtained from reduced fusion of high quality bauxite together with other raw materials in 2000℃ electric arc furnaces.

SEPPE Ceramic Proppant adapts high-quality bauxite as the main raw material, after crushing finely ground into fine powder, then it will mix with various additives, and proceed the granulation, polishing and sintering.
