Abstract

1,176,687. Moulding powders. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 25 Jan., 1968 [26 Jan., 1967], No. 4015/67. Heading B5A. [Also in Divisions B1 C1, F2, F4 and H2] A pipe for MHD apparatus is made by mixing ceric oxide and zirconia and milling in water for 36 hours in a one gallon porcelain mill with porcelain balls. The contents of the mill are filtered, dried and passed through a sieve having 10 meshes to the linear inch. The powder passing through the sieve is pressed to form rods half an inch in diameter and 5 inches long, under hydrostatic pressure of 6 tons per square inch and the rods are heated in nitrogen for two hours at 1100‹ C. The partially sintered rods are broken up in a pestle and mortar, and the pieces milled in a ring and disc mill for 1“ minutes, and the ball milled in water for a further 24 hours. The milled power is filtered, dried and passed through a sieve having 60 meshes to the linear inch, and then moulded in the form of a tube. The mould consists of a double cylindrical rubber bag formed by cementing the open end of a cylindrical bag of diameter 1À4 inches into a hole cut in the closed end of a cylindrical bag of diameter 4 inches, and turning the narrower bag inside the wider bag to form an annular space between the two rubber bags. The space is filled with the power to a depth of 6 inches, a mandrill being placed within the inner bag to retain the shape of the mould during filling. The open end of the outer bag is tied and the mould inverted in glycerol, the inner bag being filled with glycerol, and subjected to hydrostatic pressure of 25 tons per square inch. The tubular compact, so formed, is drilled to give a uniform internal diameter and is then heated to effect sintering.
