The invention discloses a preparation method of a C/C crucible upper inlaid with a ceramic lining. The method comprises the following steps: preparing colloidal ceramic modification liquid of glass fiber cloth; impregnating glass fiber cloth in the colloidal ceramic modification liquid, taking out the glass fiber cloth, and drying to obtain modified prepreg cloth; winding the modified prepreg on a winding machine to obtain a cylindrical body with a multi-layer structure; the cylindrical body is placed in a curing oven to be heated, and a preliminarily cured cylindrical body is obtained; preparing a carbon fiber pre-soaking solution, soaking carbon fiber cloth in the pre-soaking solution, and then taking out the carbon fiber cloth to obtain carbon fiber pre-soaking cloth; coating an adhesive on the outer surface of the preliminarily cured cylindrical body, and then winding a plurality of layers of carbon fiber prepreg cloth through a winding machine to obtain a composite cylindrical body; the composite cylindrical body is placed in a curing oven to be heated, and a preliminarily cured composite cylindrical body is obtained; and putting the preliminarily cured composite cylindrical body into a high-temperature furnace, heating to 1500-1800 DEG C, preserving heat for 4 hours, cooling to 150-250 DEG C along with the furnace, and discharging to obtain the C/C crucible side embedded with the ceramic lining.
本发明公开了一种镶有陶瓷内衬C/C埚帮的制备方法。其步骤是：制备玻璃纤维布的胶态陶瓷改性液；将玻璃纤维布浸渍于胶态陶瓷改性液后取出，烘干得改性预浸布；将改性预浸布在缠绕机上缠绕，得多层结构的筒状体；将筒状体置入固化炉中加热得初步固化筒状体；制备炭纤维预浸液，将炭纤维布浸渍于预浸液内后取出，得炭纤维预浸布；将初步固化筒状体的外表面涂覆粘接剂后，经缠绕机再缠绕多层炭纤维预浸布，得复合筒状体；将复合筒状体置入固化炉中加热得初步固化复合筒状体；将初步固化复合筒状体置入高温炉内，升温至1500℃～1800℃保温4小时，随炉冷却降温至150℃～250℃出炉，得镶有陶瓷内衬的C/C埚帮。
