Ceramic properties of kaolinitic clay with monoaluminum
· The effect of monoaluminum phosphate (Al(H2PO4)3) addition in the thermochemical process of a kaolinitic clay was studied and compared with the pure clay. Monoaluminum phosphate incorporation is of technological interest for the widely use of this material as an effective binder. From this point of view is important to clarify the processing strategy of kaolinitic clay-MAP based ceramics.

REF-BOND MP2 RMCIRMCI Refractory Minerals
Ref-Bond MP2 (MP2) is a family of products which are used in refractories where a source of dry P 2 O 5 is required. MP2 can be used to form cement with the addition of alkali. Other uses for MP2 include gunning dry mortars and technical cements. One of the early uses for MMP is in the area of dental investment casting.
