Sealing multiphase ceramic with adjustable thermal expansion coefficient and preparation method thereof
The invention discloses a sealing composite ceramic with an adjustable thermal expansion coefficient and a preparation method thereof, the composite ceramic comprises an expansion phase and a matrix phase, and the matrix phase selects Li2O and SiO2 as main components and at least one of B2O3, Al2O3, MgO, Na2O, ZrO2 and La2O3 as a modifier. The thermal expansion coefficient of the composite ceramic is regulated and controlled by adjusting the ratio of the high thermal expansion phase to the matrix phase. According to the preparation method, the quartz raw material is introduced into the matrix phase at one time, a long-time and complex heat treatment process is not needed to induce cristobalite growth, and the production efficiency in the sealing process of the electronic device is improved.
本发明公开一种热膨胀系数可调控的封接用复相陶瓷及其制备方法，该复相陶瓷包括膨胀相和基体相，基体相选用Li2O和SiO2为主成分，B2O3、Al2O3、MgO、Na2O、ZrO2和La2O3中的至少一种作为修饰剂。通过调节高热膨胀相与基体相的比例，对复相陶瓷的热膨胀系数进行调控。该制备方法石英原料是一次性引入基体相中，不需要长时且复杂的热处理工艺诱导方石英生长，提高了电子器件封接过程中的生产效率。
