Abstract : The mercuric iodide project at the SMART Laboratory at Kansas State University sought to understand the role of polymers in platelet growth and to maintain the procedures of Hgl2 crystal growth by vapor. In 1980 a study conducted by S.P. Faile et al. concluded that the use of polymers, specifically polyethylene, within the growth ampoule induced platelet growth. Since then, the incorporation of polymers in platelet growth has been widely employed; however, the role of polymers in platelet growth is not conclusive. Systematic experiments were carried out to determine the appropriate combination of furnace end temperature, temperature gradient, and the amount of polymers required to grow platelets of usable size. Comparison of crystal properties between crystals grown with the vertical and horizontal methods was made.
