Main characteristics
Ultra-high temperature ceramic precursor is an organic-inorganic hybrid polymer material constructed with ultra-high temperature metal elements as the main component. It is a key raw material for the preparation of ceramic matrix composite materials, ceramic fibers, and ceramic coatings. Specifically, it includes multiple brands such as zirconium carbide precursor and hafnium-tantalum carbon precursor, which have the advantages of high metal content and good applicability of the PIP process, and can meet the needs of extreme high-temperature use environments.
Application fields
Mainly used as the matrix of ultra-high temperature ceramic matrix composite materials, which can meet the high temperature resistance, oxidation resistance, erosion resistance and load-bearing requirements of materials in use environments above 2000°C. Ceramic matrix composite materials are a type of continuous fiber-toughened ceramic materials that overcome the problems of traditional ceramics such as high brittleness and poor reliability, and meet the needs of engineering applications. The ceramic matrix composite matrix plays a role in protecting fibers, providing the overall stiffness of the material, and resisting heat, water, oxygen, and airflow erosion in the use environment. It is an important component of ceramic matrix composite materials, accounting for more than 30% of its volume. The ceramic precursor impregnation method is an optional process for heterogeneous large-size ceramic matrix composites. The process performance and usage performance of the ceramic precursor play a decisive role in the comprehensive performance of the ceramic matrix composite. The company's ultra-high temperature ceramic precursor product technology comes from the Chinese Academy of Sciences and has been widely used in the aerospace field. The company has a complete after-sales service system and product secondary development capabilities, and can undertake customization of precursors with specific properties.
