PACKING STRUCTURE FOR GAS CONTAINER WITH NEEDLE-SHAPED CRYSTALLISED MATERIAL

摘要

Packing structure of a container, comprises crystal structure of xonotlite, tobermorite and/or crystallized foshagite in the form of needles of which a volume of at least 50%, a length of 2-10 mu m and a thickness of 0.2-1 mu m. An independent claim is included for a preparation of the packing structure comprises calcining a limestone pavers at a temperature of at least 850[deg]C for an hour of such that 90 wt.% have dimensions of 0.1-15 mu m, where the limestone having a purity of 92 wt.% and an open porosity of 0-25% for obtaining quick lime particles; mixing the particles in an aqueous medium with silica and optionally with other compounds for obtaining a pulp; subjecting the pulp to hydrothermal synthesis at 170-300[deg]C, for obtaining a ceramic mass; and drying the ceramic mass at 300-450[deg]C for 40-200 hours.
