Product Description
PS Ball is new material produced by supercooling method of molten slag
and in the same time transforming it into stable Spinel Structure.
It is not only used in various specific use, but also displaced with natural sand
because of excellent physical properties.
Therefore it could minimized the destruction of environment by sand collection.
Product Feature
What is PS Ball ?
PS Ball is environment-friendly product with stable molecular structure from molten slag generated a steelmaking process at steel melting shop.
The reason why PS Ball processed with SAT is structurally stabilized
Being processed with SAT, ions dissociated in ion form can be as stable oxide compound in Spinel Structure.
Spinel Structure with general chemical formula AB2O4 is octahedron shaped structure as illustration in which oxygen atom is almost filled with cube clisepacked packing, that is the structure with B atom surrounding 6 oxygen atoms in octahedron and with A atom surrounding 4 oxygen atoms.
There is Spinel as typical example in this Spinel Structure. Such as this crystal generally has solidity 5.5~8,luster like glass and high index of reflection.
Colorless and transparent one is very solid, weathering proof and corrosion proof to the extent that could be used as gem.
As the surface of this is formed with an oxide compound in Spinel Structure, ion or electron movings required in chemical reaction become difficult and therefore it forms stable compound and very strong resistance to chemical,physical cause as weathering. So, Spinel particles transformed from convert reactor slag with SAT doesn’t break out pollution problem.
