Crude kaolin (size <75 μm) was
14.45. 13.9. 1. Paper. One of the most important applications of kaolin is coating and filling paper. As a filler, the kaolin is mixed with the cellulose fibers in wood pulp and as a coating, the kaolin is mixed with water, adhesives, and various additives and coated onto the surface of the paper.
For preparing the specimens, the kaolin and bauxite rocks were sintered at 1200 °C and metakaolin was obtained by firing kaolin up to 700 °C then crushed to a fine powder and finally sieved to different particle sizes (0.2 and 1.18 mm). Bauxite and metakaolin were used as additives in (10, 20, 30, and 40 wt%) of kaolin weight.
2.1.2. Dickite. Dickite mineral was first obtained as a kaolin mineral by Allan Brugh Dick in 1908 from the Island of Anglesey, Wales-United Kingdom [33].Later on, ref. [28, 34] distinguished this from kaolinite, and determined its crystal structure and gave it the name "dickite" after its original discoverer Allan Brugh Dick [35].The structure of dickite …
