    Abstract: Micro-wave-resistant designs on crockery parts comprise silicatic materials, burnished noble metal prepns. (I). (I) comprise an organo-gold cpd., opt. mixed with organosilver-, organopalladium- and/or organoplatinum cpds.; an organic support; and a flux of organic metal cpds. contg. an organic silicon cpd. (II) having three hydrolysable gps. on the Si-atom, in amts. of 0.1-2 mols. Si per mol. of noble metal. Pref. cpd. (II) is a cpd. of formula Y3SiX in which Y is alkoxy, aryloxy, aralkoxy, acyloxy, ketoximyl, mercaptan, halogen and/or pseudohalogen and X is alkyl, aryl, aralkyl, (cyclo)alkenyl, vinyl and/or heteroatom-substd. analogues.

    Abstract: Element, preferably in panel form, for use as thermal insulation, comprising …… a) a finely dispersed, pulverulant or fibrous substance, … b) a microporous covering and … c) a gas-tight and water-proof metal-free covering. …… The element is produced by drying the pulverulant or fibrous substance, if appropriate, introducing it into a microporous covering, if appropriate, compressing it, if appropriate, and then drying it, if appropriate. After that, the pulverulant substance with the microporous covering is introduced into a gas-tight and water-proof, metal-free covering. If appropriate, this gas-tight and water-proof covering is evacuated and sealed. … …

    Abstract: Inclusion pigments (I) are based on Zr silicate (II) as shell substance, in which coloured cpds. (Fe1-xMnx)2O3 of formula (III) are enclosed as discrete phase and are mixed crystals. In (III) x is 0.05-0.60. Pref. (Fe,Mn) zeolites are used as (III). Esp. x is 0.05-0.20 or 0.30-0.60. (I) are prepd. by calcining a mixt. of ZrO2 and SiO2 or their precursors in 1:1 molar ratio for 0.5-8 hrs. at 750-1200 deg.C in the presence of mineralisers and Fe and Mn cpds. or cpds. contg. Fe and Mn with an Fe/Mn atomic ratio of 90:10 to 20:80. Pref. calcination temp. is 850-1000 deg.C for an Fe/Mn ratio of 50:50-80:20 and 1050-1200 deg.C for an Fe/Mn ratio of 50:50-30:70. Unincluded Mn and Fe cpds. are removed by treating the calcined prod. with acid.

    Abstract: Beige-brown encapsulated pigments are obtained by means of the encapsulation of iron titanates of the formula Fe2TiO5 in zirconium silicate crystals. The production takes place by calcining a mixture of zirconium oxide with a particle size distribution of /=4 m2/g, silicon dioxide and iron oxides and titanium oxides or oxide-forming Fe compounds and Ti compounds in the presence of mineralizers under oxidizing conditions at 800 DEG to 1300 DEG C.
