Preparation method of boron nitride modified short carbon fiber reinforced fused quartz ceramic
The invention discloses a preparation method of boron nitride modified short carbon fiber reinforced fused quartz ceramic, and the specific method comprises the following steps: firstly, chopping carbon fibers, immersing the chopped carbon fibers into a precursor solution in which boric acid is dissolved in methanol, introducing ammonia gas into boronized short carbon fibers under a nitrogen condition, and heating to obtain boron nitride modified short carbon fibers; adding the boron nitride modified short carbon fibers, fused quartz powder and pure water into a ball mill for mixing and ball milling; adding the mixed slurry into a plaster mold for molding; and drying the formed biscuit in a drying oven, and finally sintering the biscuit in a muffle furnace to obtain the boron nitride modified short carbon fiber reinforced fused quartz ceramic. The method is simple in process, and the prepared quartz ceramic composite material is good in mechanical property, low in heat conductivity coefficient and suitable for industrial production.
本发明公开了一种氮化硼改性短碳纤维增强熔融石英陶瓷的制备方法，具体方法包括以下步骤：首先将碳纤维短切并浸入到硼酸溶于甲醇的前驱体溶液中，将硼化的短碳纤维在氮气条件下引入氨气加热，获得氮化硼改性短碳纤维；再将氮化硼改性短碳纤维、熔融石英粉、纯水加入到球磨机进行混合球磨；把混合好的浆料加入到石膏模具中成型；成型后的素坯置于到烘箱中干燥，最后置于马弗炉中烧结，得到氮化硼改性短碳纤维增强熔融石英陶瓷。该方法工艺简单，所制备的石英陶瓷复合材料的机械性能好、导热系数低，合适工业化生产。
