The CSBR reactor (Fig. 6.4) was designed to overcome some of the issues faced with the FBR such as defluidization of the bed due to the melted plastic.The CSBR generates a vigorous contact between the different phases, and a higher collision rate significantly reduces particle agglomeration in the bed matter. A unit cell is the smallest representation of an entire crystal. All crystal lattices are built of repeating unit cells. In a unit cell, an atom's coordination number is the number of atoms it is touching. The simple cubic has a sphere at each corner of a cube. Each sphere has a coordination number of 6 and there is 1 atom per unit cell.Hence, CsBr:BiBr 3 precursor ratio of 3.0:2.0 is recommended for the formation of Cs 3 Bi 2 Br 9 phase, as evidence by material’s phase purity and optical properties.
