It helps to fill in the gaps between paper fibers, enhancing the overall quality of the paper.It fills in the gaps between the paper fibers and improves the quality of the paper.

As the calcination temperature is increased to around 900 - 1000degC, further structural changes occur.As the calcination temperatures increase to around 900-1000degC, structural changes continue. The kaolinite structure breaks down more significantly, and new phases start to form.The kaolinite breaks down and new phases begin to form. One of the important phases that can form is metakaolin.Metakaolin is one of the most important phases. Metakaolin is an amorphous material with high reactivity.Metakaolin is a highly reactive amorphous material. It can be used in the production of geopolymers.It can be used to produce geopolymers. Geopolymers are a type of alternative cementitious material.Geopolymers is a type alternative cementitious materials. In the construction industry, geopolymers made from metakaolin can offer advantages such as lower carbon emissions compared to traditional Portland cement.Geopolymers made of metakaolin in the construction industry can offer benefits such as lower emissions of carbon compared to Portland cement.

When the temperature reaches 1200 - 1300degC, the formation of mullite and cristobalite occurs.When the temperature reaches 1200-1300degC mullite and cristobalite are formed. Mullite is a high - temperature - resistant ceramic phase, and cristobalite is a polymorph of silica.Mullite is an extremely high-temperature-resistant ceramic phase. Cristobalite, on the other hand, is a polymorphic form of silica. These phases are valuable in the ceramic industry.These phases are useful in the ceramics industry. Calcined kaolin and kaolinite powder with high amounts of mullite and cristobalite can be used to make high - quality ceramics that can withstand high temperatures, such as in refractory linings for furnaces.Calcined kaolin powder and kaolinite with high amounts mullite and Cristobalite are used to make high-quality ceramics that can resist high temperatures.
