Description

一种复合陶瓷材料
技术领域
本发明涉及陶瓷技术领域，尤其涉及一种复合陶瓷材料。
背景技术
中国人早在约公元前8000－2000年(新石器时代)就发明了陶器。用陶土烧制的器皿叫陶器，用瓷土烧制的器皿叫瓷器。陶瓷则是陶器和瓷器的总称。古人称陶瓷为瓯。凡是用陶土和瓷土这两种不同性质的粘土为原料，经过配料、成型、干燥、焙烧等工艺流程制成的器物都可以叫陶瓷。
陶瓷的发展史是中华文明史的一个重要的组成部分，中国作为四大文明古国之一，为人类社会的进步和发展做出了卓越的贡献，其中陶瓷的发明和发展更具有独特的意义，中国历史上各朝各代有着不同艺术风格和不同技术特点的陶瓷制品。英文中的“china”既有中国的意思，又有陶瓷的意思，清楚地表明了中国就是“陶瓷的故乡”。早在欧洲人掌握瓷器制造技术一千多年前，汉族就已经制造出很精美的陶瓷。中国是世界上最早应用陶器的国家之一，而中国瓷器因其极高的实用性和艺术性而备受世人的推崇。
随着近代科学技术的发展，近百年来又出现了许多新的陶瓷品种。它们不再使用或很少使用粘土、长石、石英等传统陶瓷原料，而是使用其他特殊原料，甚至扩大到非硅酸盐，非氧化物的范围，并且出现了许多新的工艺。美国和欧洲一些国家的文献已将“Ceramic”一词理解为各种无机非金属固体材料的通称。因此陶瓷的含义实际上已远远超越过去狭窄的传统观念了。
现有陶瓷材料的耐急冷急热性能差，硬度较低，易氧化，容易被腐蚀、疏松、软化。
发明内容
本发明所要解决的技术问题在于提供一种耐急冷急热，硬度高，耐氧化的复合陶瓷材料。
本发明所要解决的技术问题采用以下技术方案来实现：
一种复合陶瓷材料，其原料按重量份包括：二氧化皓50-80份，二氧化硅30-50份，碳化钨4-8份，钛酸钡5-10份，二硼化镁2-4份，二氧化铈1-3份，二氧化钛1-3份，氧化铝2-5份，氧化钇0.1-0.5份，氧化铪0.2-0.6份，滑石粉5-10份，巢湖砂3-5份，磷酸二氢铝5-8份，钢纤维1-3份，碳纤维3-8份，碱式碳酸镁4-6份，微晶玻璃粉5-10份。
进一步地，还包括乌克兰蜜蜡原矿石15-20份，翠铬锂辉石20-35份。
进一步地，还包括碳酸锂5-8份，硝酸铝3-6份。
优选地，其原料按重量份包括：二氧化皓65份，二氧化硅45份，碳化钨5份，钛酸钡8份，二硼化镁3份，二氧化铈2份，二氧化钛2份，氧化铝5份，氧化钇0.3份，氧化铪0.4份，滑石粉8份，巢湖砂4份，磷酸二氢铝5份，钢纤维2份，碳纤维5份，碱式碳酸镁5份，微晶玻璃粉8份，乌克兰蜜蜡原矿石18份，翠铬锂辉石22份，碳酸锂6份，硝酸铝5份。
本发明的有益效果：本发明以二氧化皓，二氧化硅，乌克兰蜜蜡原矿石，翠铬锂辉石为主料，使其硬度大大提升，且兼具抗氧化特性，再辅以其他各原料，使整体材料具有耐酸、耐碱、耐急冷急热的特性，热稳定性能可达到在550℃～20℃急冷不裂，质量指标超过GB/T258～2002标准要求。

实施例3
一种复合陶瓷材料制作成陶瓷制品的方法，包括如下步骤：
(1)按规定重量份称取各原料；
(2)将钢纤维放置于PH值为4-5、温度为50-60℃的稀硫酸中浸洗20min，并搅拌刷除钢纤维表面的杂质，然后用清水冲洗，洗去钢纤维表面的酸液和杂质，而后烘干；
(3)将各原料进行球磨，球料比均为35:1，球磨直至上述原料均为粉末；
(4)将二氧化皓、氧化钇、氧化铪进行混合预烧，预烧温度为800℃-900℃，预烧时间为5-6h，预烧后进行二次球磨得到混合物A；
(5)将碳化钨、钛酸钡、二硼化镁进行混合预烧，预烧温度为500℃-650℃，预烧时间为3-4h，预烧后进行二次球磨得到混合物B；
(6)将钢纤维，碳纤维，碱式碳酸镁，微晶玻璃粉，乌克兰蜜蜡原矿石，翠铬锂辉石进行混合预烧，预烧温度为400℃-450℃，预烧时间为4-5h，预烧后进行二次球磨得到混合物C。
(7)将混合物A、B、C和其余原料进行机械混合，混合时间为30min-60min；
(8)将上述混合物充分加热烘干，加入有机粘结剂，用模具加压成型，得成型样品，按照25℃/min的升温速率将成型样品升温至600℃，在600℃下保温2h，再按照45℃/min的升温速率升至温度为1400-1550℃，进行高温烧结，烧结的时间为2-4h，烧结后自然降温，得到陶瓷制品。
