c. Explain the stages of ceramic processing in general! d. In ceramic material, one thing to pay attention to is porosity. How does porosity affect mechanical properties of ceramic materials?

P3 Examine the properties and applications of ceramic products manufactured using the sintering, hot pressing, chemical vapour deposition (CVD) and, reaction bonding processes.

Temperature (°C) 1. 2. What are the two characteristics of the component ions in crystalline ceramic materials that influence the crystal structure? What would the coordination number and coordination geometry be for a crystalline ceramic with a cation-anion radius ratio of 0.285? 3. Describe in general terms how a flexural test for ceramics is performed. 4. How do coarse and fine Pearlite differ and how is each formed? 5. Describe the two main ways to calculate the molecular weights of polymers. 7. 8. Draw the smallest repeating unit for each of the following polymers: a) PVC b) PS c) PP What are the corresponding recycling numbers for the polymers in Question 6? Nitrogen from a gaseous phase is to be diffused into pure iron at 700C. If the surface concentration is maintained at 0.1 wt% N, what will be the concentration 1 mm from the surface after 10 h? The diffusion coefficient for nitrogen in iron at 700C is 2.5 x 10-11 m²/s. Answer the following questions with reference to the…
