Claim Text:
1. A continuous-feed furnace assembly comprising a flow-through oven, a means for continuously adding a particulate precursor material, and a means for collecting a particulate product material, the flow-through oven defining spaced-apart particulate inlet and outlet apertures in a top thereof and an enclosed volumetric space between the particulate inlet and outlet apertures, the flow-through oven being capable of heating the enclosed volumetric space at a temperature of from 600 degrees Celsius to 1600 degrees Celsius; the means for continuously adding a first particulate material being in sequential fluid communication with the particulate inlet aperture, enclosed volumetric space, and particulate outlet aperture of the flow-through oven and the means for collecting a particulate product material, thereby establishing a particulate flow pathway, wherein a second gas inlet aperture, being in the bottom of the oven and in sequential fluid communication with the enclosed volumetric space and particulate outlet aperture of the flow-through oven and the means for collecting a particulate product material, and wherein the enclosed volumetric space does not include a frit.
