摘要

An inorganic binder system for foundry compositions including a silicate and added phosphate. The composition produces a binder having the advantageous strength properties of a silicate binder system with the dispersibility properties of a phosphate binder system. Methods of making and using the binder systems and the resulting products are of particular interest to the foundry art.
