ABSTRACT:
An ampoule contains an ingot of non-monocrystalline material. A seed of the same material but monocrystalline in nature is embedded within the ingot. A spring biases a piston to retain the seed and ingot together, even in an environment with vibrational forces. When the ingot is melted, the piston contains all of the melted material within a volume free of empty space. Upon cooling the ingot solidifies to a monocrystalline mass.
