  • Publication number: 20070003756
    Abstract: The invention relates to a method for production of a plastic body, made from a plastic obtained by means of a radical polymerisation with single- or multi-sided, inorganic coating containing silicon. The coating of a substrate is firstly achieved with a paint composition, containing inorganic particles in a solvent which can optionally contain additional flow improvers. One or more of such coated substrates can be used for the construction of a polymerisation chamber, in which the coated sides lie within the chamber. After radical polymerisation of a monomer mixture in the presence of a polymerisation initiator, the internal inorganic coating of the substrate transfers into or onto the surfaces of the radically polymerised plastic or of the plastic body. The invention further relates to the corresponding plastic body and the uses thereof.

  • Publication number: 20070003779
    Abstract: Mixed oxide powder containing indium and tin, with a proportion of indium oxide of between 90 and 98 wt. % and a BET surface area of 40 to 120 m2/g, which is in the form of aggregates having an average circumference of less than 500 nm, consists of at least 95% of an indium oxide phase and displays an oxygen content that is lower than the content that theoretically results from In2O3 and SnO2. It is produced by mixing a solution of an indium compound with a solution of a tin compound, atomising this mixture of solutions, pyrolysing the atomised mixture of solutions in a first zone of a reactor and in a second zone of the reactor, following pyrolysis, adding reducing gases to the pyrolysed mixture at one or more points in a quantity such that overall a reducing atmosphere is established in this second zone, and separating the resulting solid from the waste gases in a further, third zone, in which a reducing atmosphere likewise still prevails.
