Preparation method and preparation device of substrate
The invention provides a preparation method and a preparation device of a substrate, and belongs to the technical field of ceramic materials, and the preparation method comprises the following steps: S1, slurry preparation: dispersing ceramic powder including silicon nitride, yttrium nitrate and magnesium chloride in a water-based premixed solution; step S2, forming: adding an initiator and a catalyst into the ceramic slurry, uniformly mixing, pouring into a rotating mold, and driving the rotating mold to rotate, so that the ceramic slurry is uniformly paved on the inner surface of a sealing cavity of the rotating mold under the action of centrifugal force and is cured and formed; step S3, demolding and slicing; step S4, calcining treatment; and step S5, sintering. The method has the beneficial effects that the material strength is not obviously reduced while the high heat conductivity is obtained, the toxic and harmful problems caused by an organic solvent in tape casting are avoided, and the sintering energy consumption and the production cost are reduced; and meanwhile, by rotating the mold for forming, the operation is simple, the production efficiency is improved, and the mold is suitable for large-batch production.
本发明提供一种基板的制备方法及制备装置，属于陶瓷材料技术领域，包括：步骤S1，浆料制备：将陶瓷粉料分散于水基预混液中，陶瓷粉料包括氮化硅、硝酸钇和氯化镁；步骤S2，成型：向陶瓷浆料中加入引发剂和催化剂，混合均匀后倒入转动模具中，驱动转动模具旋转，以使陶瓷浆料在离心力作用下均匀铺覆在转动模具的密封腔内表面并固化成型；步骤S3，脱模及切片；步骤S4，煅烧处理；步骤S5，烧结。有益效果：在获得高热导率的同时保证材料强度不显著降低，避免流延成型中有机溶剂带来的有毒有害问题，降低烧结能耗和生产成本；同时通过转动模具成型，操作简单，提高了生产效率，适用于大批量生产。
