    Applications

    BINDING PROCESS:

    The application of Mono Aluminum 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 aluminum PHOSPHATE:

    Mono Aluminum 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 Aluminum 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 Aluminum Phosphate coating followed by heat treatment. Wires can also be treated thus. Mono Aluminum Phosphate not only gives the desired electrical insulation but also does away with the heat sensitivity of varnishes.
