AbstractA highlight summary of the chemistry and commercial manufacturing processes involved in making sodium silicates and sodium aluminosilicates (zeolites) is presented. Some relative and current raw material costs and energy needs, and overall qualitative economic comparisons of the various processes are discussed. Estimated world market consumption of both silicates and zeolites, by geographical areas and by major applications, is reviewed. Market volume projections into the near future are ventured on a worldwide basis, indicating substantial growth. Capacity to supply silicates in North America to 1983 is presently in place, but most other geographical areas of the world will require increased manufacturing capabilities to keep in balance with the projected market growth. It is suggested that zeolite production in the world will increase over fivefold by 1981, due principally to the expected rapid growth of its use in detergent formulations.
