A multi-inlet gas distributor for a fluidized bed chemical vapor deposition reactor that may include a distributor body having an inlet surface, an exit surface opposed to the inlet surface, and a side perimeter surface. The distributor body may also include multiple-inlets evenly spaced from each other, wherein the multiple-inlets penetrate the distributor body from the inlet surface to a first depth. The distributor body may additionally include cone-shaped apertures connecting to corresponding ones of the multiple-inlets at the first depth and extend from the first depth toward the exit surface. An apex may be formed on the exit surface at the intersection of the cone-shaped apertures.
