Ballman and co-workers have used carbon particles to determine flow patterns for polystyrene melts in plate-cone and capillary viscometers (70). Complex patterns, rather than the simple flow expected, were observed for high molecular weight samples. These may have been caused, however, by differences in viscosity between adjacent layers of pure melt and melt with suspended particles.

In the early days of electrooptic and nonlinear optic exploratory materials work in Bell Labs, A. A. Ballman and 1(35) used the following rough hewn guide to search for materials ... 

The lack of rigor (and even complete accuracy and consistency) is apparent in such an approach, but it had the virtue of actually suggesting what to do and helping to guide Ballman in his discovery of LiNbC>3, LiTa03 33) and other practical optical materials. 38)... 

Thus, we felt it particularly worthwhile to try to improve the preparation of KTP since we were willing to make the bet that drastically improved new materials were not just around the comer. Two KTP preparation methods are in general use, anhydrous flux growth as described by Loiacono and his co-workers 40) and by Ballman 41) and relatively high temperature hydrothermal growth as perfected by Belt and his colleagues. 42) We will not attempt a historical review of the development of these methods. Instead we will outline some features and preparative improvements 43,45) which we discovered as a result of a preliminary study of the process physical chemistry of hydrothermal KTP growth. 

I would like to thank my colleagues and collaborators especially E. D. Kolb, R. L. Bams, R. Belt and G. Gasharov, A. A. Ballman, K. B. McAfee, K. Nassau and W. A. Sunder for their invaluable contributions to quartz and KTP. I would like to thank J. B. MacChesney, A. Y. Cho, L. F. Thompson and R. Gottscho for patiently explaining their work and helping me to extract materials chemical examples from their achievements.

Because mold filling is a complex process, flow visualization studies have been useful and necessary, both for the actual mold design and for the mathematical simulation of the process. The first important experimental contributions were made by Gilmore and Spencer (8,9) whose work forms the basis of a review chapter by Beyer and Spencer (10). Ballman et al. (11-13) conducted mold filling experiments in the early 1960s. A decade later, a time that marks the beginning of serious efforts to solve...
