What are the differences between ceramic fiber and glass fiber?

Ceramic fiber and glass fiber are both fibrous materials used in various industries, but they differ in composition and properties. Ceramic fiber is made from inorganic materials like alumina and silica and is known for its high temperature resistance, typically used in environments up to 2000掳C. It offers better thermal insulation and is more resistant to thermal shock. Glass fiber, on the other hand, is made from glass materials and is used in applications requiring lower temperature resistance, generally up to 800掳C. It is lightweight, strong, and has good electrical insulation properties. While both are used for insulation and reinforcement, ceramic fiber is preferred for its superior heat resistance, whereas glass fiber is valued for its strength and versatility in composite materials.
