Al2SiO5OH4

Al2SiO5OH4 is a chemical compound that belongs to the group of minerals known as phyllosilicates. It is a member of the kaolinite-serpentine group, which includes minerals with similar structural characteristics. The compound is composed of aluminum, silicon, oxygen, and hydrogen atoms. Its chemical formula can be broken down as follows: Al2(SiO5)(OH)4, indicating that it contains two aluminum atoms, five oxygen atoms, and four hydroxyl groups.

Al2SiO5OH4 is typically found in clay deposits and is a common constituent of soils. It is also a major component of kaolin, a type of clay that is widely used in the ceramics industry for its white color and fine particle size. The mineral is known for its low reactivity and stability, which makes it suitable for various applications in construction materials and as a filler in paints and coatings.

The crystal structure of Al2SiO5OH4 is characterized by layers of silica tetrahedra linked by aluminum octahedra. This layered structure gives the mineral its characteristic platy or flaky form. The hydroxyl groups are located between the layers, contributing to the mineral's hydrophilic nature.

Al2SiO5OH4 is not typically found in its pure form but rather as a mixture with other minerals. Its identification often relies on techniques such as X-ray diffraction and infrared spectroscopy. The mineral's properties, including its low thermal expansion and high compressive strength, make it valuable in various industrial applications.
