Title: **Innovations of Carl F. Swinehart: A Pioneer in Macrocrystal Growth**
Introduction
Carl F. Swinehart, a distinguished inventor based in University Heights, OH, holds an impressive portfolio of 15 patents. His innovative approaches in materials science have significantly contributed to the field, particularly in the growth of macrocrystals.
Latest Patents
One of Swinehart's notable inventions is the "Crucible for Growing Macrocrystals." This cutting-edge crucible features an inner surface that is designed not to be wetted by a melt that shrinks upon solidifying. It is equipped with indentations located beneath a lateral plane through its walls, which support the ingot being grown inside. The design ensures a gap between the ingot's bottom and the crucible's inner surface, facilitating more uniform heat transfer and allowing for a controllable temperature gradient. Additionally, the bottom of the crucible is provided with at least one set of parallel grooves, with a second set that intersects at specific angles tailored to the lattice structure of the macrocrystal. This innovative configuration allows for the growth of single crystals with minimal multiplicities, enhancing the quality of the ingots produced.
