Abstract
Embodiments of the present invention disclosed herein use innovative pastes to fill surface pores (cavities) and flatten (planarize) surfaces of porous materials. A method for making a heat transfer apparatus comprises making a paste comprising particles of a first heat transfer material, a vehicle, and a binder, filling cavities on an external surface of a second heat transfer material with the paste, and drying the paste filled in the cavities so that an external, surface of the dried paste in a cavity is substantially planar with the external surface of the second heat transfer material.
