Unformatted text preview: 3 R FL fs π σ = ) 2. True or False (12 pts) Ceramics are more difficult to form than metals due to the high melting temperature as well as b r i t t l e n e s s . ( T r u e / F a l s e ) The main general differences between metals and ceramics are that ceramics have a higher K IC , a higher CTE and lower electrical conductivity. (True / False) The basic unit of the silicates is the SiO 4 4-tetrahedron. Various silicate structures arise from the different arrangements of the tetrahedron unit. (True / False) Viscosity is a measure of glassy material’s resistance to deformation. (True / False) σ ε 6 g/cm 3 ZrO 2 3.2 g/cm 3 ZrO 2...
