Abstract
Sodium alumino-silicates are produced by silicate/clay reactions under hydrothermal conditions with increased solids during processing while still producing structural materials characterized by low oil absorption values, high total pore volume and increased differential pore volumes. The products are useful as coating pigments for paper and paperboard, paper fillers, paint pigments and as reinforcing pigments for rubber.
