Abstract:
A method for vaporizing and cracking a chemical material, comprising:providing a vaporization and cracker cell apparatus comprising: a vaporization cell having a heating chamber for holding a chemical material; a heat source disposed in the heating chamber; and a thermal cracker cell communicatively connected to an outlet of the vaporization cell, the cracker cell including an elongated tube with a heating element associated therewith, the tube having a passageway with a diameter of a first dimension that narrows to a smaller second dimension by way of a tapering section in the tube, the tapering section located distally apart from an inlet of the tube, the smaller second dimension of the tube being substantially maintained from the tapering section to an exit opening of the tube; placing a preselected amount of a chemical material into the heating chamber; heating the chemical material in the heating chamber to a first temperature sufficient to vaporize the chemical material; directing the vaporized chemical material to the elongated tube; and heating the vaporized chemical material along the smaller second dimension of the passageway in the elongated tube to a higher second temperature sufficient to dissociate molecular clusters of vaporized chemical material.
