Document Type and Number:

WIPO Patent Application WO2000006519

Kind Code:

A9

Abstract:

A pumpable ceramic composition is provided comprising an inorganic oxide, potassium phosphate, and an oxide coating material. Also provided is a method for preparing pumpable ceramic-based waste forms comprising selecting inorganic oxides based on solubility, surface area and morphology criteria; mixing the selected oxides (12) with a phosphate solution (14) and waste (16) to form a first mixture (18); adding an additive to the first mixture (18) to produce a second mixture (21); adding water (22) to the second mixture (21) to produce a reactive mixture; homogenizing the reactive mixture (25); and allowing the reactive mixture to cure (28).
