Talc is a mineral silicate hydromagnesium with a chemical composition of Mg3Si4O10 (OH) 2. Talc is usually green, white, gray, brown or colorless.

Talc is a mineral with a pearly luster. Talc is the softest known mineral and is assigned a hardness of 1 on the Mohs hardness scale.

Talc is the softest known mineral and is assigned a hardness of 1 on the Mohs hardness scale. Talc has a very good slip that the plates have weak connections with each other. These plates are held together by the van der Waals force, which allows them to slide together easily.

Uses of talc

Most people use things made of talc every day, although they may not know it. Here are some uses for talc:

  • Talc in plastics:

Talc is mainly used as a filler. The plate shapes of talc particles can increase the hardness and thermal resistance of products such as polypropylene, vinyl, polyethylene, nylon and polyester and prevent them from melting.

  • Talc in ceramics:

It has been used in the production of ceramic products such as bathroom utensils, ceramic tiles, pottery and tableware.

  • Talc in color:

Most suspension dyes are mineral particles in a liquid. Talc is used as a diluent and filler in paints. The plate shapes of the talc particles improve the solid suspension, which can help the liquid paint adhere to the wall without loosening.

White talcum powder is very light. This makes it a great filler in paint. Because it causes the color to be both white and light at the same time.

Talc with low hardness is valuable. Because it causes less damage to the spray nozzle and other equipment when painting.

  • Talc on paper:

Most papers are made from a paste of organic fibers. This paste is made of wood and other organic materials. The essential mineral is added to the dough to act as a filler. When the dough is rolled into thin sheets of mineral, it fills the spaces between the fibers of the dough, resulting in a paper with a smooth surface for writing. Talc as a filler can improve opacity, brightness, whiteness as well as the ability of paper to absorb ink.
