Phase I of the program was completed. Some further work on film preparation parameters resulted in good display properties combined with lower coercive force. These results were obtained using melt compositions of 8317 Ni-Fe, high evaporation rates, and high substrate temperature. A substantial development effort in preparation of display colloid has resulted in a good understanding of the nature of the several processes that can be used. Good control in the colloid preparation is possible with a process based on forming first a seed solution of particles of small and very uniform size, then controlledly enlarging the seed particles, and finally adding the magnetic property. Techniques of panel module assembly were studied including edge encapsulation, inner bonding and silk screening. Experimental cells were made that show no sign of seal deficiency after five months.
