Geopolymeric particles, fibers, shaped articles and methods of manufacture

摘要: Shaped geopolymeric particles, fibers, and articles incorporating at least one geopolymer are provided; the having a structure that is solid, foamed, hollow or with more voids. Geopolymers formed by alkali activation of an aluminosilicate and/or aluminophosphate material. The end-products shaped as spheres, flakes, aggregates thereof articles. Such products low temperatures; wherein forming includes processing using techniques such spray drying, melt spinning, blowing. particles fibers have high chemical durability, mechanical strength, application-targeted flowability packing properties, specially suited for into composite materials, articles, use in cementitious, polymeric, paint, printing, adhesion coating applications. voids, foam-like structures adding blowing agents.
