Abstract: Flaky mica pigments coated with metal oxides are prepared by oxidizing vaporizable metal carbonyls to metal oxides with oxygen at an elevated temperature in the presence of mica flakes which are kept in motion. The amount of carbonyls introduced into the reaction zone does not exceed 5% by volume of the amount of other gases introduced. The coated mica pigments are employed as pigments in surface coatings, plastics and glasses.

Abstract: Iron oxide black pigments having improved acid resistance are obtained by treating them in aqueous suspension for 30 minutes to 200 hours at pHs from 0.5 to 14 and temperatures from 20 to 100 DEG C. The pigments aftertreated in this way are suitable for the colouring of cosmetics, pharmaceuticals and foodstuffs.

IPC: C01B17/66
Abstract: A dithionite, partic. Na dithionite, is stabilised by addn. of a combination of (a) a metallic soap of oleic acid and/or its sarcoside and/or an invert soap; (b) a 4-6C dicarboxylic acid and/or a fatty alcohol ether-sulphate of formula R'-O-CH2-CH2-O-CH2-CH2-O-SO3H (where R1 is a 12-14C hydrocarbyl). The dithionite is used e.g. in vat dyeing and in the paper industry. The stabilised dithionite is very stable w.r.t. humidity and air, is practically free from dust, and has excellent flow characteristics. It dissolves completely in water.

IPC: C25B11/04
Abstract: Bipolar electrodes having graphite as support are furnished with a layer of chromium trioxide on both the anode side and the cathode side. The chromium trioxide layer has a layer thickness of at least 10 mu m. The electrodes are produced by plasma spraying of pulverulent chromium trioxide onto a graphite support body. The electrodes can be used as bipolar electrodes in cells for the electrolysis of alkali metal chlorides.

Abstract: In an electrode suitable for electrolysis of aqueous sodium chloride or potassium chloride solutions, at least the outer layer contains spinels, specifically a mixture of the individual spinels of iron and of cobalt, the weight ratio of iron spinels: cobalt spinels being from 30:70 to 90:10. The electrodes are produced by applying a powder mixture of iron spinel and cobalt spinel to a substrate by a plasma spraying process wherein argon is used as the plasma gas and the spraying energy is from 6 to 30 kW.

Abstract: To prepare a colored pigment which has a metallic luster and consists of a metallic core whose surface is at least partially covered with an iron oxide, iron pentacarbonyl is oxidized with oxygen in a fluidized bed of the metallic cores at above 100 DEG C. The amount of iron pentacarbonyl vapor introduced into the fluidized bed must not exceed 5% by volume, based on the total gases introduced into the fluidized bed over the same period of time.
