keramická vlna

Ceramic wool is a modern inorganic fibrous material composed of fibers (most commonly aluminum, silicon, and zirconium oxides) that are produced by melting raw materials at very high temperatures (1200–1800 °C) and subsequently fiberizing them using blowing, spinning, or extrusion techniques, resulting in fine, extremely lightweight fibers. Its history dates back to the 1940s in the USA, where it was developed primarily as an insulating material for industrial furnaces, and later expanded in the 1970s in Asia (China, Japan). The technological production process includes melting ceramic raw materials, fiber formation, possible surface treatments, and the manufacture of final products such as mats, strips, textile felts, papers, cords, and technical fabrics. In the textile industry, ceramic wool is valued for its extreme heat resistance (withstanding temperatures above 1200 °C), low thermal conductivity, chemical inertness, resistance to thermal shock, low weight, and sound-insulating properties. It is widely used in technical textiles—thermal insulation systems, heat-resistant fabrics, protective clothing accessories (gloves, coats), as well as in the automotive industry, construction, filtration, and energy sectors. Its limitations include health and environmental concerns when handling fine fibers.
