The aluminum phosphate binder consists of a combination of orthophosphoric acid (H3PO4) or monoaluminum phosphate [A1(H2P04)3] and aluminum oxide (fused alumina, AI2O3). Upon heating to elevated temperatures the two constituents interact, and aluminum orthophosphate (AIPO4) is formed as the final product of the reaction at temperatures above about 500 °C. This is a cementing process that results in the development of a hardened material. Aluminum phosphate binder is widely employed in refractory concrete applications, and is discussed in more detail in Chapter 23. 

Improved bond strength in ceramic bodies is attained with mixtures of monoaluminum phosphate and colloidal silica when used with finely divided refractory powders of zircon, zirconia, or alumina (480). The reaction of P,0, with silica at relatively low temperature develops high bond strength in refractory compositions thus silica sol may be mixed with ammonium phosphate or other P,Os precursors at relatively low pH and used in minimal quantities as a binder in refractories (481,482). According to Lee, the binding properties of colloidal silica are improved by adding a soluble quaternary ammonium silicate such as tetramethylammonium silicate which is sufficiently alkaline to interact with the colloidal silica and cdhlesce it in a cement structure (483).
