在最佳配比及烧结制度下,将一定比例的含氟金云母与氧化铝混合料辊轧后的薄片同氧化铝基体薄片交替地作层状叠合.经1600℃烧结后,在含氟金云母层内形成了K2O—MgO-Al2O3-SiO2系的玻璃陶瓷.复合后的层状陶瓷其断裂途径呈台阶状,同无层的氧化铝基体相比,其弯曲强度基本相同,但其断裂韧性K1c值却提高了近60%
At the optimized composition of the PVA/Water/alumina, the thin sheets of fluorophlogopite mica powder doped with alumina were stacked with the thin sheets of alumina matrix, rolled to form laminated material. Sintered at 1600℃ for 40 minutes, the thin sh
