Abstract

304,729. Metallges. Akt.-Ges. Jan. 25, 1928, [Convention date]. Porous refractory substances.-A porous heatinsulating refractory material is formed of magnesium ortho-silicate either synthetically produced or a natural product such as olivine, peredolite or dunnite, by agglomerating grains of suitable size with or without a, binding agent. Chemical compounds having a cementing action may be used. The porosity of the product may be increased by adding to the granular raw materials substances which generate gases when heated or when water is added, such as magnesium carbonate, magnesium nitrate, and aluminium nitrate. The magnesium orthosilicate may be formed from serpentine or other magnesium hydro-silicates by heating with magnesium oxide, magnesite, &c. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the addition of substances which are eliminated by heat to form pores, such as sawdust, peat powder, cork waste, coal, maize grains and rice husks, and also specifies metals such as aluminum and calcium, and carbides as substances for generating gases when water is added. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 260,298, 283,791, 284,576, 301,547, and 307,391, [all in Class 22, Cements &c.].
