  • Patent number: 9950451
    Abstract: A method of manufacture of products from geopolymer composite shaped in a mold which is filled by casting of geopolymer composite in form of a precursor and after its hardening the casting is taken out from the mold and the casting surface is provided with a metallic layer. Before metal-plating casting surface with absorption capacity greater than 5% is treated to make it chemically stable so that pH of a leachate from 100 g of the bulk product in 1000 g distilled water after 24 hours does not exceed 9. In order to reduce the absorption capacity of the casting surface it is penetrated with polymer substances or particles of a non-porous filler are added into the geopolymer composite in the precursor state.

  • Publication number: 20140367881
    Abstract: A method of making products with a functional relief surface (2) with high resolution up to 10 nm, which is copied from a template (1) or carrier of the negative relief of the surface, the so-called master. The template (1) of the relief surface (2) is provided with at least one layer of geopolymer composite, applied in a precursor state (3), in form of a liquid dispersion or grout in plastic or thixotropic condition, whose thickness is the same or greater than the depth of the template relief (1), at temperatures in the interval from the temperature corresponding to properties of the precursor (3) to the temperature corresponding to thermal decomposition of the precursor (3), and after hardening of geopolymer composite the layer or layers is/are separated from the template (1).
