The bonding of refractory concretes, masses and mortars is a subject of very special importance in the ceramics field.

In order to obtain an effective cold bond using MONO Aluminium Phosphate up to 10% of bond clay should be included with the MONO Aluminium Phosphate.

BINDING PROCESS :

The application of MONO ALUMINIUM PHOSPHATE as a bonding agent for refractory products is based on its reaction with weak basic oxides (e.g. Al2O3) resulting firstly in the formation of orthophosphates.


APPLICATION OF MONO ALUMINIUM PHOSPHATE :

MONO ALUMINIUM PHOSPHATE is used for bonding refractory materials, which have an Al2O3 content of 60-90% as, for instance, corundum, mullite and sintered bauxite. Further more, MONO ALUMINIUM PHOSPHATE produces a very good bond with fire clay, silicon carbide, and chromites within certain limitations, with quartz.


APPLICATION IN ELECTRICAL INDUSTRY :

According to modern practice, varnish coating of silicon steel strip cores of electrical motors are being replaced by MONO ALUMINIUM PHOSPHATE coating followed by heat treatment. Wires can also be treated thus. MONO ALUMINIUM PHOSPHATE not only gives the desired electrical insulation but also does away with the heat sensitivity of varnishes.
