Summary

Rods of lithium aluminosilicate were nucleated at 450 °C for 3 hours in a conventional furnace. The bars were then cut into discs and crystals were grown over a range of temperatures using both microwave and conventional heating. X-ray diffraction analysis was performed on the samples to determine the crystalline phases present. Peak intensities were compared to determine the relative percent crystallinity due to differing heat-treatments. The effect of the heat-treatment parameters using both microwave and conventional heating on the extent of crystallization is discussed.
