Founded in 2005 in China, SEPPE is the world’s leading manufacturer of Aluminum Oxide materials in severe

conditions - including sintered bauxite, fused alumina, garnet and foundry ceramics materials - used in

hydraulic fracking, abrasive grindings, refractory, waterjet cutting, blasting, foundries and casting plants,

with more than hundreds of application worldwide.

SEPPE’s mission is to research, manufacture and market reliable, high quality products which are able to

provide environmentally sustainable industrial solutions worldwide.

Based on its patented technologies and mining resources, SEPPE produces fused aluminum oxides, sintered

bauxite, and foundry mullite ceramsite etc. Its products are distributed worldwide through subsidiaries and


SEPPE operates in three main business areas:
- The Abrasives industry
- The Hydraulic fracturing projects
- The Foundry&casting industry

Mullite sand / powder, produced through high temperature calcined process, is a kind of high quality casting

sand made from the of high quality Kaolin mines. The main crystalline phase is mullite . It has good performance

on lower thermal expansion rate, uniform expansion , better anti vibration, good hardness etc. It is very

good to be used for precision casting.

1. High refractor, Lower thermal expansion rate;
2. Good thermal and chemical stability;
3. Good grain shape, uniform particle size distribution ;
