Dillard, B. M.

The calcium chromate synthesis process developed at General Electric Neutron Devices Department was investigated at a ten-pound yield level by producing forty-six batches of the product at this level. The effect of reaction temperature, recycling filtrate, recycling ammonia, and various washing procedures on product purity and yield was determined. Results from these investigations led to the development of a standard operating procedure for repeatedly producing calcium chromate to meet stated specifications. Five ten-pound batches were consecutively prepared to meet these specifications. These were blended and samples were analyzed.
