Raw Material

Volcanic rock with high potential 

The almost unlimited availability of high quality raw materials of volcanic origin is the basis for the development of the ASA.TEC-fiber.

Volcanic rock originates at a depth of hundreds of kilometers as the liquid magma of the earth's upper mantle. When magma reaches the surface it cools to igneous rock and can be mined as a raw material. This volcanic rock contains in addition to its main components silicon and oxygen, a distinctive composition of elements such as calcium, magnesium, iron, sodium, potassium, aluminum and titanium.
