Abstract
1,226,553. Sintered porous Si 3 N 4 and ZrO 2 . ROLLS ROYCE Ltd. 7 June, 1968 [27 June 1967], No. 29507/67. Heading C1A. [Also in’ Division C7] Sintered cellular refractory or metallic bodies e.g. Si 3 N 4 and ZrO 2 are made from a slurry of the powder, a liquid binder and particles of an organic material. The slurry is solidified, heated in air to carbonize the binder and organic material, without destroying the solid, further heating to oxidize the carbon and finally heating to sinter. Rate of temperature rise, at least up to first heating step does not exceed T C./hour= 80/Y +¢ where Y is diameter in inches of largest sphere which can be contained in solid prior to heating. Binder may be an epoxy, phenolic or methacrylate resin, and organic material may be hollow or solid particles of epoxy, natural resins, waxes or sugar. Slurry is cast, solidified and machined to shape. Layers of slurry containing different concentrations and sizes of organic particles may be cast to form a body with varying porosity and sintering may be effected in a reducing, neutral or reacting atmosphere. Si 3 N 4 foam is produced from a Si slurry which is sintered in N 2
