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.
 
Above illustration showing that XRD analytic result of furnace slag(PS Ball) super cooled with high-speed air , the formation of Dicalcium Ferrite (2CaO•Fe2O3) and Larnite(β -2CaO•SiO2) which are CaO compound can be identificated.
Like this chemical elements of furnace slag(PS Ball) super cooled with high-speed air are mainly composed of CaO, Fe2O3, SiO2,but showing below 15% of F-CaO( when this reached above 1% exist risk of collapse), which means that as you know in XRD analytic result most of CaO exists in compound state, that is spinel structure, of 2CaO•Fe2O3 and 2CaO•SiO2 reacting with Fe2O3, SiO2.　

Diversified Applications of PS Ball

1. Abrasive Blasting Material
One of the major application area of PS Ball in Korea is Abrasive Blasting Material.
PS Ball can be used as a substitute for Garnet or Copper Slag and sometimes it can be used as a substitute for Steel Ball.

2. Weight Material
PS Ball is heavier than sand, therefore it can be used as a mixing material in a counter balance.

3. Casting Sand
PS Ball can be used as Casting Sand for the casting of nonferrous metals, with its special properties such as hardness, spherical shape, uniformed size and permeable effect.

4. Water treatment
With its uniform and spherical shape, PS Ball can be used as filtration media for recycling treatment of industrial waste water. It has been proved to have higher efficiency than river sand for pollution removal.

5. Roofing Granules
PS Ball can be used widely as high resistant granules to produce asphalt roofing shingles. It has been proved that the appearance and useful life of shingles applied with PS Ball are better than crushed rock.

6. Non-slip Material
PS Ball has the property of high coefficient of friction and high resistant to slip.
By applying it for the covering on the road, non-slip effect can be achieved greatly with durability of abrasion

7. Reinforcement  Material
Due to its special property of coherence with asphalt or concrete, and durability of abrasion, PS Ball can be used as Repair or Reinforcement Material with high efficiency.

8. Poly-concrete Material
PS Ball can be used as one of the main material for the production of Poly-concrete products. Using its property of cement-friendly, low water absorption and hardness, excellent Poly-con product can be made with big cost saving.

9. Sand-pile Material
For hardening of the ground of seashore or riverside, usually sand has been applied for pumping water. Using PS Ball, it can be done with high efficiency due to PS Ball’s property of hardness, uniform and spherical shape.

10. Road Pavement Material

ⅰ) For Concrete Road
       Concrete mixture using PS Ball can reduce the cost of cement and chemical admixture.
       Besides, the durability will be highly increased.
  ⅱ) For Asphalt Road
       Black color of road can last longer using PS ball than conventional road, and  the durability will be increased remarkably.

11. Permeable Reactive Material
Utilizing the properties of its hardness, uniform and spherical shape, PS Ball can be used as Permeable Reactive Material in waste (food or garbage) dumping area.
