Abstract

202,698. Frosell, O. May 13, 1922. Compositions containing oxychlorides.-Magnesia is made into a paste with water and moulded into articles which are allowed to set at a pressure of 80 lbs. per sq. in. or more. Hot moulds may be employed with hydraulic pressure up to 3000 lbs., or the composition may be moulded under a pressure of 1500 to 1600 lbs., and then steamed at 80 lbs. If the magnesia contains lime ammonium chloride may be added in such proportions, viz., two parts of commercial sal ammoniac for one of lime, that it reacts with the lime, and not with the magnesia. Fillers, such as wood flour, cork, sawdust, rock dust or crushed stone, silicia infusorial earth or kieselguhr, asbestos, &c. may be employed, and examples are given of compositions containing such fillers. Reference has been directed by the Comptroller to Specification 25884/04, [Class 22, Cements &c.].
