Ceramic fiber shaped products are made from a mixture of refractory fibers through vacuum forming, offering superior high-temperature performance and self-supporting strength. The products exhibit low shrinkage within their operating temperature range and maintain high thermal insulation, lightweight, and resistance to thermal shock. Unburned shaped products can be easily cut or machined. During use, the products demonstrate excellent wear resistance and resistance to spalling, and are not corroded by most molten metals. Our ceramic fiber shaped products come in various sizes and shapes, including tubular, conical, domed, and square box shapes, and can be produced according to customer requirements, with options for surface hardening or complete hardening as needed.
