ABSTRACT:
Stable and storable solid compositions which are capable of readily dispersing in an aqueous medium and causing the formed aqueous system to exhibit a high degree of pseudoplasticity. The solid composition comprises a mixture of particulate alkali metal aluminate and a solid, water soluble zinc, iron or aluminum metal salt of an inorganic mineral acid selected from halogen or nitric acid. The aluminate and metal salt should be present in a ratio such that the composition is capable of forming an aqueous system having an alkaline pH of at least 8.
