摘要

Disposable hollow bodies consist of a thin ceramic material opt. converted to the metallic state. Claimed prodn. is by forming and ceramicising a sol-gel or a polymer film loaded with metal, metal oxide or a ceramic (or ceramic precursor). USE/ADVANTAGE - The disposable bodies can be containers (e.g. for use in fast food outlets), the use of the bodies also being claimed as plates, refuse containers or ultrafiltration or sepn. membranes, with zeolite-based bodies also being used as moulds or insulation for ice-cubes.
