A method is provided for joining (gluing) individual silicon nitride components used in the preparation of structural objects of different types of silicon nitride ceramic with a broad range of porosity (from zero to ~23%). The method includes preparation of an adhesive mixture based on silicon nitride, successive application of the mixture to component surfaces being joined, and firing of the joined object at 1000°C with exposure for 2 h. The glued joint is distinguished by high adhesive strength, which makes it possible to prepare objects of complex structure by this method. © 2011 Springer Science+Business Media, Inc.

The effect is considered of such operating properties as the design of a molding unit and the method of drying gypsum molds, on the life of the forming surface of molding units. Avoidance of the disadvantages revealed combined with results obtained in part 1 (E. I. Sudal'tsev, D. V. Kharitonov, and A. A. Anashkina, "Increase in the service life of forming surfaces of molding units. Part 1. Study of the improvement of molding unit forming surface material quality," Novye Ogneupory, No. 2, 30-38 (2010).) of this work make it possible to increase the service life of molds by more than a factor of three © 2010 Springer Science+Business Media, Inc.
