Production process of low-cost high-purity zirconium diboride or titanium diboride
The invention relates to a production process of low-cost high-purity zirconium diboride or titanium diboride, which comprises the following steps of: putting metal carbide, boric anhydride and graphite powder serving as raw material powder and magnesium powder serving as an auxiliary agent into a ball-milling tank of a vacuum ball mill, adding an adhesive for ball-milling to obtain a ball-milled mixture, and pressing the ball-milled mixture into a cylindrical mixture bar; protective gas is introduced into the push boat type atmosphere sintering furnace, and power is supplied for heating; the method comprises the following steps: loading a cylindrical mixed bar into a material boat, pushing the material boat into a heating carbon tube, igniting an ignition valve after 5 minutes, keeping the temperature of the material at 1400-1900 DEG C, opening a boat inlet, pushing the material boat filled with the material into the heating carbon tube from a furnace head tube, ejecting the fired material out of the heating carbon tube to enter a furnace tail tube, and cooling the fired material through heat exchange of cooling water in a water jacket. Taking out and crushing to obtain a product. The method has the advantages of easily available raw materials, low production cost, simple process, easiness in control, high product purity, no obvious impure phase and suitability for industrial production.
一种低成本高纯二硼化锆或二硼化钛的生产工艺，将金属碳化物、硼酐和石墨粉为原料粉，镁粉为辅助剂，放入真空球磨机的球磨罐中，并加入粘合剂进行球磨，得到球磨混合料并压制成圆柱状混合料棒；向推舟式气氛烧结炉内通入保护气体，送电升温；将圆柱状混合料棒装入料舟后，推送至加热碳管内，5分钟后，将点火阀点燃，物料在1400℃～1900℃保温后，打开进舟口，将装好物料的料舟由炉头管推送至加热碳管内，烧制好的物料被顶出加热碳管进入炉尾管，经过水套内的冷却水热交换冷却后，取出破碎，得到产品。优点是：原料易得且生产成本低，工艺简单，容易控制，产品纯度高，无明显杂相，适合工业化生产。
