Summary:Previously abstracted from original as item 9109-E6-c-0078. Experimental studies on the alumino-silicae refractory, SK-13, the atmosphere during annealing and the temperature and duration of annealing had a significant effect on the microstructure, phase composition and properties of the ceramic. Annealing in a reducing atmosphere at 1380 deg C in a tunnel kiln, in preference to an electric furnace, produced the most homogenous structure, containing secondary mullite, zircon and cordierite. Annealing for 17 h improved the dispersion of the crystals and increased the temperature stability, chemical resistance and strength of the material.
