Custom Ceramic Fiber

Ceramic fiber is a fibrous lightweight refractory material with the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, and small specific heat. While providing a series of ceramic fiber products, Alfa Chemistry also has the ability to develop and customize innovative ceramic fibers, including ceramic oxide fibers and ceramic non-oxide fibers. Our fiber development department has a strong technical base and a team of well-trained and experienced experts.

Optional Service Items

Based on their unique properties, ceramic fibers have attracted extensive attention in high temperature applications. Combining rich experience in R&D and production and advanced technical expertise, Alfa Chemistry is committed to providing customers with satisfactory customized development services for ceramic fibers, as well as accurate and detailed analysis and test results.

  • Optional Ceramic Fiber Composition
    For ceramic oxide fibers, optional compositions include Al2O3, SiO2, Al2O3-SiO2 mixtures, zirconia (ZrO2), and the like. For ceramic non-oxide fibers, optional compositions include silicon carbide (SiC), boron (B), boron nitride (BN), silicon oxynitride (SiNO), SiCN, Si-Al-ON, Si-BCN, and so on. In addition, polymer-derived ceramic fibers, such as those derived from polysilanes/polycarbosilanes, polysilazane, polycarbosilazane, polyborosilazane, and polysiloxanes, are also the focus of our research and services.

Optional Ceramic Fiber Composition

  • Optional Ceramic Fiber Physical Parameter
    We can customize the size, morphology and other parameters of ceramic fibers according to your requirement, such as continuous fibers (long fibers), discontinuous fibers (short fibers). In addition to regular circular cross-sections, we can also customize ceramic fibers with special structures, such as hollow structures.

  • Optional Analytical Testing Service
    We have comprehensive and systematic analytical testing capabilities to provide accurate characterization services at all stages of project development as required. Our analytical capabilities include, but are not limited to, chemical composition analysis, mechanical properties analysis, microstructure analysis, solid phase and morphology analysis, and thermal analysis, etc. Among them, the thermal properties of ceramic fibers are one of the most important parameters. We usually evaluate the heat resistance of ceramic fibers according to the shrinkage change of the sample heating line and the degree of crystallization.
