Title: Method for preparing porous shells or gels from glass particles
Usefulness: Method for preparing porous shells or gels from glass particles
Summary: The shells or porous gels may be filled with a liquid, gas or solid material, e.g. a chemotherapeutic drug (claimed). They can also be heat treated and used (i) as a filler in paints, resins, polymers or metals, (ii) as a bone growth or repair agent when administered to mammals, (iii) as a filter, (iv) as a precursor for nano sized powders, (v) as a thin surface film, (vi) to remove hazardous species such as chromates, arsenates and uranates from solution, or (vi) as a catalyst support medium (claimed).
Novelty: Preparation of shells or porous gels from glass particles, useful for forming carriers for chemotherapeutic drugs, as fillers, as bone growth or repair agents, for removal of hazardous agents or as catalyst support
