A photovoltaic crucible mold release compound includes a powder mixture comprising silicon nitride powder having 1 ppm of impurities or less and silicon dioxide 1 ppm of impurities or less mixed in with the silicon nitride powder until the gray of the silicon nitride powder turns lighter in color which is from 1% silicon dioxide in weight up to 50% silicon dioxide in weight. Also included is a binder having a liquid. The powder mixture is mixed with the binder. The binder can be ethanol, water or alcohol. A photovoltaic crucible mold release compound can also include a photovoltaic crucible mold, so that the mold release compound is applied to an inside surface of the photovoltaic crucible mold to a thickness of 75 to 1500 microns.
