What is the feature that distinguishes Q7.3 glass from the traditional and new Q7.4 Q7.9 ceramics? What type of atomic bonding characterizes the ceramics? What is clay, used in making ceramic products? Q What does the term refractory mean? 7.11 (1) Compare briefly the structures among them and (2) compare briefly the properties among them. (1) Name the type of bonding to characterize; (2) explain briefly such type of bonding. Part of the solution to this question is provided in the e- textbook. However, you need to (1) provide a definition, (2) name its main composition, and (3) give 2 examples of ceramic products based on clay. (1) Provide a definition, (2) name at least 2 materials that are refractory, and (3) give at least 2 applications based on refractory materials.
