Abstract
Young modulus and toughness (KIC) of bulk solar grade silicon (SoG-Si) obtained by directional solidification of metallurgical grade silicon were determined. The Young modulus was measured by the technique of impulse excitation of vibration and KIC was determined using the indentation method. Measurement values agree well with those available in the literature. The indentation method proved to be a reliable, relatively simple, inexpensive, and fast experimental method to measure KIC in SoG-Si.
