  • Method of manufacturing glass and compositions thereof
    Patent number: 7803730
    Abstract: A solid state particle agglomerate and method for producing the solid state particle agglomerate are provided. The alkaline earth metal source material, aluminum source material and silicon source material that comprise the solid state particle agglomerate are uniformly distributed and in close proximity within the solid state particle agglomerate, enabling the solid state particle agglomerate to form glass in a more energy efficient manner when heated.

  • Fluidized reaction of synthetic silicates
    Patent number: 6569793
    Abstract: A process is disclosed in which coarse silica, calcium oxides and magnesium oxides are treated in a ball mill together with grinding aids and cold-strength binders. This material is then agglomerated with water to produce a product that reacts at elevated temperatures, e.g. in a fluidized bed reactor, to produce synthetic silicates.
