Production method for preparing boron carbide-silicon carbide composite ceramic by utilizing silicon carbide crystal grinding waste liquid
The invention discloses a production method for preparing boron carbide-silicon carbide composite ceramics by utilizing silicon carbide crystal grinding waste liquid, and belongs to the technical field of preparation of boron carbide-silicon carbide composite ceramics. The technical problem to be solved by the invention is to recycle waste materials. The method comprises the following steps: stirring the silicon carbide crystal grinding waste liquid of which the grinding material is boron carbide, separating by using a filter to obtain particles, washing to obtain first filter residues, soaking in a hydrochloric acid solution, fully stirring for 60-120 minutes, washing, drying, carrying out ball milling, putting into a mold, carrying out cold isostatic pressing molding, putting a molded blank into a vacuum electric furnace, and sintering, increasing temperature to 300 DEG C at the speed of 2-5 DEG C/min and keeping for 30 min, then increasing the temperature to 1600-2000 DEG C at the speed of 3-5 DEG C/min and keeping for 30 min, finally, lowering the temperature to 1000 DEG C at the speed of 3-8 DEG C/min, and turning a power source of the vacuum electric furnace so that the temperature of the vacuum electric can be cooled naturally to room temperature. The method is used for recycling the silicon carbide crystal grinding waste liquid.
一种利用碳化硅晶体研磨废液制备碳化硼‑碳化硅复合陶瓷的生产方法，它属于碳化硼‑碳化硅复合陶瓷制备技术领域。本发明要解决的技术问题为废料的回收再利用。本发明将磨料为碳化硼的碳化硅晶体研磨废液搅拌后，利用过滤器进行分离，得到颗粒，水洗后得到第一滤渣加入盐酸溶液浸泡并充分搅拌60‑120min，然后水洗、烘干、球磨后置于模具中于进行冷等静压成型，将成型胚料放入真空电炉内烧制，以2‑5℃/min升温至300℃并保温30min，再以3‑5℃/min升温至1600‑2000℃并保温30min，最后以3‑8℃/min降温至1000℃，关闭真空电炉电源使其自然冷却至室温。本发明用于碳化硅晶体研磨废液的回收。
