www-personal.umich.edu2. Mechanical properties versus degree of crystallinity: Crystalline phases are stronger. At low T’s, crystalline and non-crystalline phases are brittle. At high T’s approaching Tm, non-crystalline phases are ductile. NaCl 34 801 MgO 366 2800 BeO 310 2585 TiC 207 3180 SiC 345 >2800 Al2O3 310 2050 Ceramic: E (GPa) = Tm (C) = (at room ...
