Talc – the softest mineral in the world, functional and environmentally friendly.
LITHOS has a long experience in the processing and application development of talc. Based on high quality raw materials different product lines are created and produced.
What is talc (soapstone)?
Talc is the world's softest mineral. All talc ores are soft, platy, water repellent and chemically inert, but no two talcs are the same. Talc is a vital part of our everyday life. Talc is found in products such as magazines, car and house polymers, paints and tiles. Talc is a naturly layered hydrated magnesium sheet silicate that has a platelet structure with the chemical formula Mg3 Si4 O10 (OH)2.
The elementary sheet is composed of a layer of magnesium-oxygen/hydroxyl octahedra, sandwiched between two layers of siliconoxygen tetrahedra. The main or basal surfaces of this elementary sheet do not contain hydroxyl groups or active ions, which explains talc's hydrophobicity and inertness.
- The softest mineral (Mohs hardness 1)
- Hydrophobic (water-repellent), not soluble in water
- Organophile (binds readily with organic materials)
- Chemically inert, acid and alkali resistant
- Electrically and thermally insulating
