M. Ganster & M. Steiner introduced and studied the concept of gb-closed set for general topology which motivates to introduce gb-closed sets in bitopological spaces, symbolized by ij-gb-closed sets, being the main object of this paper. This paper contains the properties of the above sets and introduces two new bitopological spaces ij-T* b1/2 and ij-*T b1/2 spaces as applications. Also the relations of these spaces with ij-T1/2 and ij-T-b1/2 spaces have been found a place in this paper.
