(0.8 pts TOTAL) Zircоniа (ZrO2) is а cerаmic material that has been used in оrthоpedic implants for ceramic femoral head hip implants. One company, St. Gobain Desmarquest, supplied the zirconia femoral heads to multiple companies. Initially St. Gobain Desmarquest used a batch furnace technique to sinter the ZrO2 powder with yttrium oxide (Y2O3) to 1500°C at 1000 atmospheres of pressure thereby generating a tetragonal crystal structure of ZrO2. This structure imparted strong mechanical properties commonly observed with zirconia ceramics with high fracture strength. However, in 1998 St. Gobain Desmarquest altered the heating technique to a tunnel furnace mechanism whereby ceramic materials were sintered on a conveyer belt system as opposed to batch system. In early 2001, femoral heads manufactured with the tunnel furnace technique began to fracture and fail at a significantly higher rate thus resulting in a recall of non-implanted products. Investigators suspected that an alternate less stable crystal structure was formed during the tunnel furnace treatment compared to the batch furnace treatment. The thermal profile for samples prepared with each method is displayed below.Answer the question below pertaining to this problem: (0.4 pts) Name and briefly describe one experimental analysis technique you could use to investigate this theory. (0.4 pts) Briefly discuss ONE potential mechanism in which the thermal treatment may influence the crystal structure.
