11.5.1 Process Description1-2. Refractories are materials that provide linings for high-temperature furnaces and other processing units. Refractories must be able to withstand physical wear, high temperatures (above 538°C [1000°F]), and corrosion by chemical agents. There are two general classifications of refractories, clay and nonclay.

The applicable process of synthesizing multiple zeolites from kaolin for nucleation, octahedron formation and generation of various types zeolite illustrates in Fig. 4, two steps can be used to expound the synthesis process: (i) Metakaolinization-which involves the transformation of kaolin to metakaolin.
When meta-kaolin is added to a lime-treated lateritic soil it generally tends to lower the pH of the sample in the short term, but eventually attains an equilibrium range of pH values. This is in contrast to the behavior of samples treated with lime only, which exhibited a continuous decline in pH values and took longer to reach equilibrium.
