Preparation method of insulating ceramic material
The invention belongs to the technical field of ceramics, and particularly relates to a preparation method of an insulating ceramic material, which comprises the following steps: by taking bis (3-chloropropyl) dichlorosilane and 3-chloropropyl trichlorosilane as raw materials, spraying and depositing to obtain silicon porous particles, and stirring and permeating by utilizing aluminum isopropoxide to form silicon-aluminum composite particles; and finally, mixing aluminum isopropoxide, trichloromethylsilane and the silicon-aluminum composite particles, standing, heating and sintering to obtain the insulating ceramic material. The problem of brittleness of an existing aluminum oxide ceramic material is solved, a silicon porous material is utilized to form a porous structure, a silicon hydroxyl active system is provided, active connection and compactness with aluminum oxide are improved, the porous structure can form a frame structure which is through inside and outside, the internal toughness of the ceramic is improved, and the service life of the ceramic is prolonged. Therefore, the purpose of improving brittleness is achieved.
本发明属于陶瓷技术领域，具体涉及一种绝缘陶瓷材料的制备方法，以双（3‑氯丙基）二氯硅烷和3‑氯丙基三氯硅烷为原料，经喷雾和沉积得到硅系多孔颗粒，并利用异丙醇铝搅拌渗透形成硅铝复合颗粒，最后异丙醇铝、三氯甲基硅烷和硅铝复合颗粒混合，静置、加热和烧结，得到绝缘陶瓷材料。本发明解决了现有氧化铝陶瓷材料的脆性问题，利用硅系多孔材料形成多孔结构，不仅提供了硅羟基活性体系，提升与氧化铝的活性连接与致密性，而且多孔结构能够形成内外通透的框架结构，提高了陶瓷内部韧性，从而达到改善脆性的目的。
