What are the differences between ceramic fibers and glass fibers?

Ceramic fibers and glass fibers are both high-temperature resistant fibers, but they differ in composition, properties, and applications. Ceramic fibers are made from inorganic non-metallic materials and have higher melting points, better thermal insulation, and higher strength compared to glass fibers. They are often used in high-temperature environments such as aerospace and automotive industries. Glass fibers, on the other hand, are made from silica-based materials and are known for their electrical insulation, corrosion resistance, and tensile strength. They are widely used in construction, electronics, and composite materials. While both types of fibers have their unique advantages, ceramic fibers generally offer superior thermal and mechanical properties at high temperatures.
