What is kaolin made of?
Kaolin, which is also known as china clay, is a white stone; its main component is kaolinite, which results from the erosion of feldspar. 15 Kaolin is treated with a surface layer of polyacrylic acid and sodium salt in order to make it easier to disperse the substance evenly.
What is porcelain made of?
Porcelain was invented in ancient China, made from a hard, white clay known for its fineness and strength. This ceramic material proved so useful, particularly for dinnerware, it spread across the world, nicknamed after its country of origin.
What is the chemical composition of kaolinite?
From Simple English Wikipedia, the free encyclopedia Kaolinite or Kaolin is a clay mineral. It is in a group with the chemical composition Al 2 Si 2 O 5 (OH) 4. It is a layered silicate mineral, with one tetrahedral sheet linked through oxygen atoms to one octahedral sheet of alumina.
What is the morphology of kaolin crystals?
The morphology of the kaolin crystals is plate-like. The c-axis of the kaolinite crystal is perpendicular to the basal plane. A crystal system of the kaolinite is triclinic, the space group is P1, and lattice parameters are a = 0,515 nm, b = 0,895 nm, c = 0,740 nm, ? = 91,68°, ? = 104,87°, ? = 89,9° [11].
