Sealing slurry, preparation method of sealing slurry, composite ceramic substrate and preparation method of composite ceramic substrate
The invention relates to sealing slurry and a preparation method thereof, and a composite ceramic substrate and a preparation method thereof. The sealing slurry comprises the following components in percentage by mass: 70%-78.5% of a network forming agent; 1.5%-5% of a nucleating agent; 2%-7% of a regulator; the sum of the network forming agent, the nucleating agent and the regulator is 77-82%; 0.03% to 0.35% of a toughening agent; 0.3%-1.5% of a curing agent; 17%-21% of a solvent or a diluent; after coating the sealing slurry, sintering, discharging water, discharging glue and crystallizing to form a beta-eucryptite microcrystalline phase; and the expansion coefficient of the beta-eucryptite microcrystalline phase is-9.1 * 10 <-6 > to-0.8 * 10 <-6 >/K. The technical problem to be solved by the invention is how to provide the sealing slurry, so that a composite ceramic substrate sealed by using the sealing slurry is not easy to crack a sealing material and is high in percent of pass, thereby being more suitable for application.
本发明是关于一种封接浆料及其制备方法，复合陶瓷基板及其制备方法。以质量百分含量计，该封接浆料包括：网络形成剂，70％～78.5％；形核剂，1.5％～5％；调整剂，2％～7％；所述网络形成剂、形核剂和调整剂的总和为77％～82％；增韧剂，0.03％～0.35％；固化剂，0.3％～1.5％；和溶剂或稀释剂，17％～21％；封接浆料涂覆后，烧结，排水，排胶，晶化，形成β‑锂霞石微晶相；β‑锂霞石微晶相的膨胀系数为‑9.1×10‑6～‑0.8×10‑6/K。本发明所要解决的技术问题是如何提供一种封接浆料，使应用该封接浆料封接的复合陶瓷基板不易发生封接材料的开裂，合格率高，从而更加适合适用。
