目前我国各行业生产中普遍使用的阀门为金属阀门，金属阀门的使用已有上百年的历史，其间虽然也经过结构及材料的改进，但受金属材料自身条件的限制，越来越不能适应高磨损、强腐蚀等恶劣工况的需要。主要体现在使用寿命短，泄露严重大大影响了系统运行的稳定性。传统的金属阀门急需从材料、设计及制造工艺等方面的彻底革新。先进陶瓷材料作为二十一世纪的新材料，已被越来越多的科学工作者所重视，把它应用于工业阀门是一项大胆和有益的创新。 陶瓷材料变形量很小，比金属具有高得多的结合强度，一般情况下组成陶瓷材料的晶体离子半径小，而且离子电价高，配位数大，这些性质决定了陶瓷材料的抗拉强度、抗压强度、弹性模量、硬度等都非常高。然而陶瓷本身的“脆”及难加工限制了它的应用范围，近十几年来，由于马氏体相变增韧技术、复合材科技术及纳米陶瓷概念的发展及进步，已使陶瓷的“脆性”得到了大大改进，其韧性和强度得到了极大的提高，应用范围不断扩展。 近年来，新型陶瓷材料在石油、化工、机械等领域的应用非常活跃，利用陶瓷的耐磨性、耐腐性制作耐磨耐腐零件部代替金属材料，是近几年来高技术材料市场的重要发展方向之一。 陶瓷阀门具有巨大社会经济效益： 1.采用高技术新型陶瓷结构材料制作阀门的密封部件和易损部件，提高了阀门产品的耐磨性、防腐性及密封性，大大延长了阀门的使用寿命。 2.陶瓷阀门的使用可以大降低阀门的维修更换次数，提高配套设备运行系统的安全性、稳定性，减轻工人的劳动强度，节约设备修理费用。 3.陶瓷阀门的使用能提高工业管路系统的密封性，同时能{zd0}限度的杜绝泄露，对环境保护将起到积极的推进作用。 4.制造陶瓷的原料广泛，成本低廉，用铝、碳、硅等普通无素就能制造出性能优越的陶瓷材料，可以节约大量金属材料和稀有的矿产资源。 耐磨陶瓷阀门主要应用于电力、石油、化工、冶金、采矿、污水处理等工业领域，尤其是面对高磨损、强腐蚀、高温、高压等恶劣工况，更显示出它{zy1}的性能。它能满足高磨损、强腐蚀的使用环境，尤其突出的特点是超长的使用寿命，其性能价格比远远优于其它同类金属阀门。随着科学技术的不断发展和进步，陶瓷材料从配方、成型、加工及装配工艺等各方面的技术更加趋于成熟和完备，陶瓷阀门以其优异的性能越来得到业内人士的认同。利用制造陶瓷阀门的成功经验还可以推广应用于更广泛的工程领域。

At present the production of various industries in China commonly used in valve metal valve, metal valve used has a century of history, during which although improved through the structure and materials, but the metal itself by the conditions, more and more can not adapt to high wear, high corrosion bad condition, needs. Mainly in short service life, greatly affected the disclosure of a serious system stability. Traditional metal valves needed from materials, design and manufacturing processes, etc. revolutionized. Advanced ceramic materials as 21-century new materials, has been more and more valued by scientists, it is a bold used in industrial valves and useful innovation. Deformation of ceramic materials is very small, much higher than the metal with a combination of strength, generally composed of ceramic materials crystal ionic radius, and ion price high, a large coordination number, these properties determine the tensile strength of ceramicmaterials , compressive strength, elastic modulus, hardness and so very high. However, ceramic itself, "brittle" and difficult to machine limits its scope of application, the last decade, due to martensitic transformation toughening technology, composite materials and nano-ceramic Branch Technical development of the concept and progress, has led to ceramics " brittle, "has been greatly improved, its toughness and strength has been greatly improved, ever-expanding range of applications. In recent years, new ceramic materials in petroleum, chemical, mechanical, and other fields are very active, using ceramic wear resistance, corrosion resistance and wear-resistant corrosion-resistant parts made of metal materials to replace the Department, is an important market in recent years high-tech materials development directions. Ceramic valve with great social and economic benefits: 1. Using high-tech ceramic structural materials of new valve sealing parts and wearing parts, valve products increased wear resistance, corrosion protection and sealing, greatly extended the life of the valve. 2. The use of ceramic valve can replace a large number of lower valve repair, improve the supporting equipment operation system security, stability, reduce labor intensity, saving equipment repair costs. 3. Ceramic valves can increase the tightness of industrial piping systems, while able to prevent disclosure of the maximum of environmental protection will play a positive role in pushing forward. 4. Manufacturing ceramic materials wide, low cost, aluminum, carbon, silicon and other common factors can not create superior performance ceramic materials, can save a lot of metal materials and scarce mineral resources. Wear-resistant ceramic valves are mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of high wear, high corrosion, high temperature, high pressure and other adverse conditions, but also demonstrated its superior performance. It can meet the high wear and tear, the use of highly corrosive environment, in particular outstanding feature is the long service life, its cost performance is far better than other comparable metal valves. With the continuous development of science and technology and progress of, ceramic materials from the formulation, molding, machining and assembly process and other aspects of the technique is more mature and complete, its outstanding performance ceramic valve increasingly recognized by the industry. Using the successful experience of manufacturing ceramic valves can also be applied to a wider range of engineering fields.
