The invention relates to the technical field of monocrystalline silicon preparation, in particular to a graphite felt preform as well as a preparation method and application thereof. The graphite felt prefabricated body comprises a graphite felt substrate and a coating arranged on the surface of the graphite felt substrate; the coating is mainly prepared from silicon carbide, a film-forming agent, a stabilizer and an organic solvent in a mass ratio of (40-50): (10-20): (15-25): (5-35). According to the graphite felt preform, the silicon carbide compound coating is arranged on the graphite felt substrate, so that the problem of high cost caused by corrosion, pollution and crushing after the existing graphite felt is used in a furnace for a long time can be solved, the overall service life is prolonged, and the cost is reduced.
本发明涉及单晶硅制备技术领域，具体而言，涉及一种石墨毡预制体及其制备方法和应用。石墨毡预制体包括石墨毡基底和设置在石墨毡基底表面上的涂层；涂层主要由质量比为40～50：10～20：15～25：5～35的碳化硅、成膜剂、稳定剂和有机溶剂制得。该石墨毡预制体通过在石墨毡基底上设置碳化硅复配涂层，能够解决现有石墨毡在炉内长时间使用后被腐蚀、污染、粉碎从而导致成本高的问题，提升了整体寿命，降低了成本。
