Densified system

The pan is not a densifying system, but rather a layering system. Therefore, the end results may not meet marketing requirements or duplicate the final production product. There are ways to increase the density of the green granules, but you can be too successful and end up with a product which will not disperse or break up, at application.

Densely packed cementitious materials are commonly also called also DSP materials, which is an acronym for Densified Systems containing homogeneously arranged ultrafine Particles. The alternative term reactive powder concrete is also used. In principle these are cementitious materials formed by the Itydration of densely packed particles of an inoiganic binder in combination with ultrafine particles of a second, less reactive or non-reactive filler. Some additional particulate materials may also be present. 

Oxyfluoride compounds and highly densified ceramics that are related to lithium niobate, LiNbOs, were obtained in the system ... 

If the composite is left only partially densified, it can be used as a filter for high temperature filtering systems with high collection efficiency as required in direct coal-fired gas and steam turbines. Similar systems are considered for particulate filtering in diesel engines by a carbon foam or felt coated with silicon carbide by CVI. 

Searles Lake. Searles Lake is a large evaporite deposit about 78 km square and 46 rn deep. It contains a complex mixed salt system that includes trona along with potassium, boron, and other salts (23,24). North American Chemical Company recovers soda ash (1.0 x 10° t/yr) from the lake by carbonating and cooling the brine to crystallize sodium bicarbonate (25). The bicarbonate is filtered and calcined to light soda ash which is densified by conversion to the monohydrate followed by calcining. The procedure results in a dense ash with properties equivalent to Wyoming trona derived ash.
