Paragraph 1 - Compare and contrast the crystal structures and crystal chemistry of quartz‚ α-FePO4 and β-FePO4. Both α-FePO4 (space group: P3121) and α-quartz (space group: P3121 and P3221) belong to the trigonal crystal system‚ while β- FePO4 (space group: P6422) and β-quartz (space group: P6222 and P6422) belong to the hexagonal crystal system. At relatively low temperature‚ FePO4 is tetrahedral in structure. This is similar to the tetrahedral structure of quartz. As temperature increases‚ the
