Preparation method for in-situ synthesis of boron nitride fiber reinforced and toughened boron nitride ceramic
The invention belongs to the technical field of ceramic engineering and science, and particularly relates to a preparation method for in-situ synthesis of boron nitride fiber reinforced and toughened boron nitride ceramic, the method comprises the following steps: raw material proportioning: selecting hexagonal boron nitride and a toughening agent as raw materials; ball milling: adding a ball milling medium and ball milling beads into the raw materials, and performing ball milling in a ball mill; filtering: filtering the ball-milled slurry with a screen to obtain slurry; drying and sieving: drying the slurry in a drying box, crushing and grinding the dried raw materials, and sieving into powder; sintering: putting the obtained powder into a mold, putting the mold into a hot-pressing sintering furnace, introducing nitrogen or ammonia gas, and sintering under a sintering condition to obtain the boron nitride fiber reinforced and toughened boron nitride ceramic. Compared with the prior art, not only is the toughness of the boron nitride ceramic improved, but also the original electrical conductivity, thermal stability and other properties of the boron nitride ceramic are not influenced, and the preparation method is suitable for industrial production. The method has obvious superiority.
本发明属于陶瓷工程与科学技术领域，具体涉及一种原位合成氮化硼纤维增强增韧氮化硼陶瓷的制备方法，所述方法为：原料配比：选取六方氮化硼、增韧剂作为原料；球磨：将所述原料加入球磨介质和球磨珠放入球磨机中球磨；过滤：将球磨后的浆料用筛网进行过滤获得浆料；干燥过筛：将所述浆料置于干燥箱中干燥，干燥后的原料经过破碎研磨后过筛成粉体状；烧结：将获得的粉体状置于模具中，放入热压烧结炉中，通入氮气或氨气，在烧结条件下进行烧制得到氮化硼纤维增强增韧的氮化硼陶瓷，本发明相对于现有技术，不仅提高了氮化硼陶瓷的韧性，而且还不影响其原有的导电性、热稳定性等性能，具有明显的优越性。
