Abstract
A magnesia refractory is made by treating sea water or other natural brine containing convertible magnesium salts, with calcined dolomite or dolomitic limestone, which may be in the form of a slurry, without the application of heat, removing the precipitated magnesium hydroxide and subjecting it to calcination to form a clinker. Substances suitable for binding agents may be introduced into the brine or slurry before precipitation, or mixed with the precipitate or incorporated in the water used for washing the precipitate. Suitable substances are the compounds of calcium, silicon, iron, aluminium, chromium or zirconium. The precipitate may then be concentrated and directly introduced into a rotary kiln or applied as a paste to a flat surface or network on which it may be dried in a tunnel drier. The dried product may then be calcined and ground. The particles are said to be elongated and thereby are more easily bound together. The preparation of a brick is described wherein the clinker is crushed, sieved and graded, the graded material being then remixed in the proper proportions, moulded and calcined. Specification 482,339 is referred to.ALSO:A magnesia refractory is made by treating sea water or other natural brine containing convertible magnesium salts, with calcined dolomite or dolomitic limestone which may be in the form of a slurry, without the application of heat, removing the precipitated magnesium hydroxide and subjecting it to calcination to form a clinker.
