Question - Chemical Engineering Material - In crystal material, hexagonal crystal system could form 4-digit index in certain direction of solid. For [1(-1)0] direction in the hexagonal crystal systems of particular catalyst applied in fume removal of incinerator, what is the four-digit index for this direction? Hint : The transformation equations between the 3-digit [h’k’l’] and the 4-digit [hkil] indices are : h = (1/3) (2h’ – k’); i = - (h + k); k = (1/3) (2k’ – h’); l = l’. A. [(-1)100] B. [1(-1)00] C. [(-1)000] D. [00(-1)(-1)] E. [(-1)0(-1)0]
Answer Posted / kang chuen tat
Answer : h = (1/3) [ 2 - (-1) ] = 1; k = (1/3) ( - 2 - 1 ) = -1; i = - ( 1 - 1 ) = 0; l = i = 0. Solution is [1(-1)00]. Answer is B.
