WebAug 5, 2015 · Here, C ij are conventional aggregate elastic constants and B T is bulk modulus. We represent, C 44 and C S as the shear and tetragonal moduli of a cubic crystal. Table 2 illustrates the computed values of bulk modulus (B T), shear moduli (C 44) and tetragonal moduli (C S) which validates the elastic stability criteria for 3C SiC in B3 phase. WebA high modulus of elasticity furthermore results in excellent dimensional stability. Additionally, there is the zero porosity and low pore density of the ceramic material. Due to its resistance to almost all chemicals as well as water/steam at several hundred degrees Celsius, SiC is superior to other ceramic and metallic materials.
