| Abstract: | The resistance to erosion and thermal shock of several ceramic materials, particularly alumina, was measured. The alumina specimens were made by pressing and sintering finely ground particles. The objective was to fabricate wear-resistant components for a burner assembly used for the atomization and combustion of abrasive coal-liquid fuels. The test procedures are described, and their use demonstrated to identify a commercially available material from which shapes were prepared to a dimensional accuracy of 0.5%, of 99.5% theoretical density, and having optimized erosion and thermal shock resistance. |
