The samples were collected from three different locations in the territory, namely Sheda, Abaji and Karimu, and labeled A, B, and C. In order to project a better representation of the territory, the samples were mined from ten cites each.

They often are used to pump gases and vapours from a system to create a vacuum. The refractoriness of all the samples were 1300o C and this showed that they could be used as insulating materials.

Experimental investigation of a novel steam ejector refrigerator suitable for solar energy applications. In this Paper, a new approach for controlling microstructure development during hot working process by percentage of volume fraction recrystallization is proposed. One of the approaches is based on the Optimal Control theory and involves the developing of state space models to describe the material behavior and the mechanics of the process. The elemental composition of synthesized sample was confirmed by EDS analysis. An investigation on the properties of termite hill as refractory material for furnace lining: Indian Foundry Journal.

Solid density averaged 3.18g/cm3 with 0% saw dust and 2.91g/cm 3 with 40% saw dust, still bringing them closer to the international range of 2.3-3.5g/cm3 . The simulation is done on various values for percentage of volume fraction recrystallization using both the controllers by MATLAB simulink toolbox.
