AB  - Single crystal of Lithium Potassium sulphate is grown by slow evaporation technique at room temperature. The grown crystal is characterized by Vickers   micro hardness test. It  is carried  out  by  over a load with a  range of 10 – 100 gm on  the  selected  smooth  plane  surface of the crystal.  Vickers’s hardness values (Hv) are calculated for selected applied load and it is found to be increasing with the   increasing applied load. The  Meyer’s  index  number (n) is .calculated  from  the  Vickers hardness  number and   it  confirms that the  grown material  belongs  to  soft material  category.  The Elastic stiffness constant (C11) is calculated using Wooster’s empirical relation. Further the Yield strength (σv), Brittleness index (B), and the Fracture toughness (Kc) are calculated to the grown LKS crystals.
