摘要:
The invention relates to articles comprising a metal surface provided with a glass-, glass-ceramic- or ceramic-type protective layer, characterized in that the protective layer comprises a base layer comprising a matrix made of an alkali and/or alkaline earth silicate and an alkali metal- and alkaline earth metal-free top layer comprising a matrix made of an oxidic silicon compound, and to a method for the manufacture of said articles.The articles comprising the protective layer exhibit high chemical resistance and improved non-stick properties. They are characterized in particular by high dishwasher resistance.

摘要:
The present invention relates to a method for producing hydrogen-free carbon nitrides, in particular carbon nitrides of the stoichiometry C3N4. The carbon nitrides are synthesized using hydrogen-free reactants, namely inorganic isocyanates that release only CO2 when thermally treated. In particular, a way of cheaply and efficiently providing carbonitrides, advantageously in the form of powders or coatings, is proposed.
摘要:
The present invention relates to methods for producing inorganic resins, comprising the polymerisation of at least one hydrogen-free, inorganic isocyanate which may be converted into a pure, hydrogen-free polymer by CO2 abstraction, to resins which are produced by this method, and to the use of such resins for producing coatings.
