The zero-divisor graph of a commutative ring R is defined to be a graph with all the elements of ring R as vertices and two distinct vertices x, y adjacent if and only if  Thereafter, it got modified by considering only the non-zero zero-divisors as the vertices of the zero-divisor graph denoted by  and two distinct vertices x, y adjacent if and only if  The graph generated by taking one copy of G, referred to as the centre graph, and  copies of H, referred to as the outer graph, and making the i^th vertex of G adjacent to every vertex of the i^th copy of H is the Corona product of G and H  denoted by  In this paper, we determine the graph properties such as diameter, girth, clique number, vertex chromatic number, and independence number of Corona product of zero-divisor graphs of direct product of finite fields.
