    摘要： There are prepared aqueous solutions of cationic organosilicon compounds which are produced by reacting an alkoxysilylalkyl halide of the formula (RO).sub.3-n R.sub.n.sup.1 --Si--R.sup.2 --X (I) where R is C.sub.1 to C.sub.5 alkyl, methoxy, ethoxy, phenyl, or C.sub.5 to C.sub.8 cycloalkyl; R.sup.1 is C.sub.1 to C.sub.5 alkyl, phenyl, tolyl, benzyl, or C.sub.5 to C.sub.8 cycloalkyl; R.sup.2 is a divalent ethylenic double bond free hydrocarbon group having 3 to 8 carbon atoms, n is zero, 1 or 2 and X is chlorine, bromine, or iodine with a tertiary amine of the formula R.sup.3 NR.sup.4 R.sup.5 (II) where R.sup.3, R.sup.4, and R.sup.5 are the same or different and each is an alkyl group or benzyl in which the number of carbon atoms of the alkyl group or the alkyl groups together is up to 30 or R.sup.4 and .sup.5 together with the nitrogen atom, as well as in a given case a further hetero atom selected from the group consisting of oxygen, nitrogen, and sulfur is a univalent five to eight membered heterocyclic ring having three to seven --CH.sub.2 -- groups in the heterocyclic ring, or R.sup.5 is a C.sub.3 to C.sub.12 cycloalkyl group in aqueous medium at a temperature from room temperature (e.g. about 20.degree. C.) to 300.degree. C. at a mole ratio of (I) to (II) between 1:0.8 to 1:1,2 and in a given case under pressure.

    摘要： A preferably platelike form body for use as heat insulation, consisting of:a) a finely divided, powdery or fibrous material,b) a microporous casing andc) a gas and watertight casing.The form body is produced by optionally drying the powdery or fibrous material, optionally placing it into a microporous casing, optionally pressing it and then optionally drying it. Then, the powdery material is placed with the microporous casing into a gas and watertight casing. This gas and watertight casing is optionally evacuated and sealed.

    摘要： Inclusion pigments are discolored having zirconium silicate as a casing component and chromium (III) oxide (Cr.sub.2 O.sub.3) as a discrete, included color compound. The included Cr.sub.2 O.sub.3 has a D.sub.50 value in the range of 0.1 to 3.0 .mu.m and a brilliant light green color. Contrary to non-included Cr.sub.2 O.sub.3 of identical value, the pigments of the present invention may be used for the preparation of decorations without problems and difficulties in their application and maintaining sharp lines and contours. The pigments are suitable for direct pressing and high temperature firing processes. They are prepared by fusing a mixture of zirconium dioxide, silicon dioxide, mineralizators and chromium oxide.
