At 1,400 C, it is observed that the Young’s modulus of the sample was 90.8042 MPa, it, however, increased to 157.5683 MPa as the sintering temperature was increased to 1,500 C. Further increase in the sintering temperature of the sample to 1,600°C is observed to lead to an increase in Young’s modulus of the sample to 192.5311 MPa.
