Phase III of the project will consist of final refinements and commercialization of the sensor-first for use in laboratories, then for use on line in industrial processes. It is anticipated that a commercial version of the sensor should be available by the end of 1992. These particle size distribution measurements will greatly enhance on-line process control in a large number of industries. The initial market is expected to be in the chemicals industry, where slurries are widely used. Within the chemicals industry, early applications of the sensor are expected to include the production of clays and pigments such as titanium dioxide.
Titanium dioxide is a relatively costly pigment used to whiten products ranging from paint to paper.
Clays are common industrial materials used in applications including enamel and porcelain products, brick and title, and industrial filters. Clay is also used as the support material for a large number of industrial catalysts. The potential of the new sensor is even greater if additional applications, both within the chemicals industry and in other industrial sectors, are considered. The cost of reworking or regrinding such material to bring it up to commercial quality can be substantial. Control of particle size distribution can greatly reduce this cost and lead to the development of new and improved products.
