Brown fused aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well.
Because Brown Fused Aluminum Oxide has a high bulk density and high hardness making it the perfect media for removing rust, mill scale, and surface contamination. The consistent particle size allows for a uniform surface finish and coverage.
Additionally, BFA has a low friability which allows it to be recirculated on average, up to seven times. These characteristics reduce abrasive consumption, clean up, and disposal costs, increasing profitability.
Terbium Gallium Garnet(TGG) as a magneto-optical crystal, is an optimum material for Faraday devices (Rotator and Isolator) in the range from 400nm-1100nm, excluding 470-500nm.The Faraday rotator consists of a TGG rod contained inside a special designed magnet. The rotation sense of the polarization of a light beam passing through the rotator only depends on the direction of the magnetic field and not on the direction of propagation of the light beam. The optical isolator is a Faraday rotator set between two suitably aligned polarizers which allows a light beam to pass through in one direction only.Photonchina TGG has a combination of excellent properties such as large Verdet constant, low light loss, high thermal conductance and high light damage threshold which makes it a unique material for Faraday devices particularly suitable for YAG lasers and Ti: sapphire tunable lasers, ring lasers and seed injected lasers.

Garnet is a natural product with chemically inert, non-toxic metals and crystalline silica. With its good hardness, garnet has been used as a gemstone and blasting abrasives.
Features:
Low Dust: The high intrinsic tenacity and a high proportion of the material itself fast the settlement rate and significantly reduce the dust emissions and dust coming from the workpiece, minimizing cleaning effort sandblasting, reducing pollution of the work area.
Excellent Surface Quality: It can deep into the voids and uneven parts to clean, thereby completely remove rust, soluble salts and other contaminants; surface blasting process without inserts, will not adversely dimples and pits, easy access to 50-70 microns surface roughness.
Recyclable: Its excellent tenacity and lower brittleness can lower damage rates and higher productivity. Depending on the specific application, it can be reused up to 3 times.
Lower Production Costs: The paintâ??s adhesion and corrosion resistance depending on the cleanliness and surface roughness of the base material. Using garnet abrasive can greatly save the amount of paint by completely eliminate adverse spurs and pits.
Improve Health and Safety: Its non-toxic characteristics can greatly reducing silicosis, leaching of metals or radioactive contamination risks.
Application:
1. Blasting abrasives: Derusting of steel structure, hull, Bridges;
2. Water jet cutting: Cutting metal, stone, glass;
3. Grinding media: Grinding marble, optical lens, glass, leather and other materials;
4. Filter medium of chemical, petroleum, pharmacy, water treatment;
