先进陶瓷的发展与展望
2021-04-09

在近20年,应用领域从单一的军事、航空航天推广到环保、新能源、电子信息等更为广泛的民用市场,陶瓷材料也从结构陶瓷、功能陶瓷向结构—功能一体化发展。针对目前国内先进陶瓷现状,仍需从几个方面进行重点研究开发:

1、陶瓷技术的基础理论研究和结构设计需要匹配应用领域对先进陶瓷的发展要求,能够对新体系、新产品、新应用和批量化转化提供技术保障;

2、 陶瓷粉体技术的研究与产业化,要打破高端粉体仍受国外制约的现状,满足陶瓷材料发展的基本需要;

3、增韧技术的研究是突破先进陶瓷应用局限性的关键之一,强韧化技术将实现先进陶瓷应用翻天覆地的变化;

4、降低先进陶瓷生产成本是突破先进陶瓷应用局限性的另一个关键因素;

5、注射成型、注凝成型和固体无模成型技术将成为最具批量化应用潜力的成型技术,微波烧结、放电等离子烧结技术将会给陶瓷材料性能带来质的飞跃;

6、 结合“十三五”规划的要求和工业发展的要求,能源转化载体的储能陶瓷、在环境保护中作用突出的过滤陶瓷(膜)等功能。

我国从事先进陶瓷研究的单位有300多家,技术积累日益丰厚,当今先进陶瓷的发展不再局限于传统技术,而更多的是与现代信息、自动化技术、不同材料的结合而形成新的技术科学,先进陶瓷发展的新时代即将到来。

先进陶瓷属于脆性材料,硬度高、脆性大。由于陶瓷加工性能差,加工难度大,稍有不慎就可能产生裂纹或者破坏,因此不断开发高效率、高质量、低成本的陶瓷材料精密加工技术已经成为国内外陶瓷领域的热点。

In the past 20 years, the field of application has been promoted from a single military and aerospace industry to a broader civilian market such as environmental protection, new energy and electronic information. Ceramic materials have also evolved from structural ceramics and functional ceramics to structural-functional integration. For the current status of the domestic advanced ceramics, still need to focus on several aspects of research and development:
1. The basic theoretical research and structural design of ceramic technology need to match the development requirements of advanced ceramics in application fields and provide technical support for new systems, new products, new applications and batch conversion;
2, ceramic powder technology research and industrialization, to break the high-end powder is still subject to the status of foreign constraints to meet the basic needs of the development of ceramic materials;
3, toughening technology research is to break through the limitations of advanced ceramic applications, one of the keys, toughening technology will achieve dramatic changes in the application of advanced ceramics;
4, to reduce the cost of advanced ceramic production is to break through the limitations of advanced ceramic applications, another key factor;
5, injection molding, injection molding and solid molding technology will become the most batch of potential application of molding technology, microwave sintering, discharge plasma sintering technology will bring a qualitative leap in the performance of ceramic materials;
6. Combined with the requirements of the "13th Five-Year Plan" and requirements of industrial development, energy-saving ceramic storage ceramics, and filtration ceramics (membranes) that play an important role in environmental protection.
 
There are more than 300 units engaged in the research of advanced ceramics in our country. The accumulation of technology is increasingly lucrative. The development of today's advanced ceramics is no longer confined to the traditional techniques, but more is the combination of modern information, automation technology and different materials to form new technologies A new era of scientific and advanced ceramic development is coming.
Advanced ceramics are brittle materials, high hardness, brittleness. Due to the poor processing performance of ceramics, the processing is difficult and the cracks may be generated or damaged by slight mistake. Therefore, the continuous development of high-efficiency, high-quality and low-cost ceramic material precision processing technology has become a hot spot in the field of ceramics at home and abroad.
