Corundum has many colors as it contains different pigment particles. According to the color of corundum, it can be divided into Brown fused alumina, white fused alumina, black fused alumina, etc. They are all belong to artificial abrasives and widely used for abrasive industry.

SEPPE produces oil fracturing proppant which is the best quality materials. Then how to recognize high quality oil fracturing proppant?

Proppants used should be permeable or permittive to gas under high pressures; the interstitial space between particles should be sufficiently large, yet have the mechanical strength to withstand closure stresses to hold fractures open after the fracturing pressure is withdrawn.

Referred to as refractory brick. Refractory material with a certain shape and size. According to the preparation process, it can be divided into bricks, brick, electric melting brick (Cast Brick), the refractory insulating bricks; according to the shape and size, it can be divided into standard brick, ordinary brick, specific rotation.

The word cenosphere comes from two Greek words: kenos (hollow) and sphaira (sphere). Cenospheres are in fact hollow lightweight alumino-silicate bubbles.

Garnet has been used for decades as an abrasive in water jet cutting and sand blasting because of its superior physical properties. When added to high pressure streams of water, garnet abrasive is capable of cutting through tough materials including steel, aluminum, stone, and Inconel.With the varie

Mullite sand is aluminum silicate refractory materials, normally used in stainless steel precision casting technology.

Water-jet cutting, also known as water cutting, namely high pressure water jet cutting technology. Water-jet cutting is a generic term used to describe equipment that uses a high pressure stream of water for cutting or cleaning purposes.

White corundum powder, white, strong cutting force. Chemical stability, and has a good insulation. Scope: wet or dry jet sand, suitable for crystal, the electronics industry, ultra-fine grinding and polishing and production of advanced refractory materials.

SEPPE garnet is a high hardness, high density granular filter media. It can be used extremely effectively as the lower strata in a dual media filter bed. It has a high specific gravity as well as its chemical and abrasive resistance makes garnet an ideal filter media.
