The current situation of boron nitride ceramic fibers

Boron nitride ceramic fiber is a polycrystalline fiber primarily composed of boron nitride products, boasting excellent thermal insulation and high temperature resistance. It is primarily used as a reinforcement agent for ceramic matrix composites and as a window component for aircraft micro-antennas.

Currently, boron nitride ceramic fibers are primarily prepared using the phase deposition method, boron nitride product fibers are mainly prepared using the organic precursor method, and boron nitride product composite materials are mainly prepared using the coating method and cold pressing method. Among them, research on boron nitride product fibers; #039; Research on silk fibroin indicates that the preparation of fibers with excellent performance is a research hotspot in this field. The key to the industrialization of fibers lies in finding a method suitable for large-scale production under relatively mild reaction conditions. The industrialization of fibers will broaden their application in composite materials.

Fiber materials related to boron nitride ceramic fibers and boron nitride product materials and their characteristics exhibit unique properties, including high specific modulus, good corrosion resistance and dielectric properties, strong neutron absorption capacity, and good compatibility with composite materials. Metals, resins, and ceramics are widely used in composite materials and military equipment to strengthen automobile bodies.

Currently, experts both domestically and internationally have conducted extensive research on the preparation of boron nitride ceramic fibers. Fibers made from organic precursors are suitable for industrial production, boasting high production efficiency, fine fibers, and resistance to weaving. However, the formation of complex components alters the preparation conditions and various applications of different fiber varieties. Therefore, in recent years, the chemical method for preparing boron nitride ceramic fibers has emerged as an ideal approach.

The above is the current status of boron nitride ceramic fibers, which generally pose little harm to water. Do not allow undiluted or large amounts of the product to come into contact with groundwater, waterways, or sewage systems, and do not discharge the material into the surrounding environment.
