Metalzed ceramics, as a unique material, incorporate the properties of metals and ceramics, with excellent physical, chemical and mechanical properties. The production process mainly includes the following links: raw material selection, mixture preparation, molding, sintering and subsequent processing. Metalzed ceramic products belong to special composite materials, which aggregate the advantages of a variety of materials, and have a wide range of applications in aerospace, electronics, energy and other fields. It is hoped that metallized ceramics can be used in daily life, and can “fly into ordinary people’s homes like mobile phones”.
The process for making metallized ceramics is as follows:
- Raw material selection: According to the performance requirements of metallized ceramics, appropriate metal oxides, non-metallic oxides, such as alumina and aluminum nitride and additives, are selected as raw materials.
- Mixture preparation: the selected raw materials are mixed and ground, so that they are evenly dispersed to form a mixture, and form a special preparation.
- Forming: the mixture is made into the desired shape through the molding process, such as injection molding, pressing molding, etc. This process is just like the process of fine ceramics.
- Sintering: the formed blank body is sintered at high temperature to form metallized ceramic products with certain properties. This process is like the process of fine ceramics, but the temperature, pressure and fusion time should be controlled.
- Follow-up processing: according to the needs, the sintering of metallized ceramic products after cutting, grinding, drilling and other processing processes, especially in the handover of different materials, to be more careful to meet the use requirements, precision ceramic precision and strength, hardness requirements.
The characteristics of metallated ceramics are as follows:
- Excellent physical properties: Metallized ceramics have high strength, hardness, thermal stability, electrical insulation and other properties.
- Chemical stability: Metallized ceramics have good corrosion resistance, wear resistance and oxidation resistance.
- Functionality: Metlized ceramics can design their properties according to the needs to realize electromagnetic shielding, sound absorption, radiation resistance and other functions.
The biggest difficulty in the production process of metallized ceramics lies in the sintering link. How to realize the low temperature sintering and improve the sintering density and uniformity is the key technical problem. To solve this problem, we can realize the high performance and wide application of metallized ceramics by optimizing the raw material ratio, improving the molding process, and adjusting the sintering atmosphere. The biggest difficulty of metallized ceramics is that how to achieve uniform grain growth and maintain the integrity of the ceramics is a technical problem. Because metallized ceramics need to be sintering at high temperature, it is easy to produce abnormal growth of grains, leading to the decline of the mechanical properties of ceramic products. Moreover, how to realize the electrical conductivity of metals while maintaining the insulating properties of ceramics is also a challenge.
To solve these problems, we are constantly exploring new preparation processes and techniques. For example, using advanced molding techniques such as gel injection molding and hot pressing molding yields a more uniform mixture and finer ceramic particles. Moreover, by adjusting the sintering conditions, such as temperature, pressure and atmosphere, the growth of the grains can be controlled and the ceramic density can be increased.
In addition, we are committed to developing new metallized ceramic materials to meet your needs for various special applications. For example, metallized ceramics with high temperature superconducting properties can be used in fields such as power transmission and maglev trains. At the same time, the metallized ceramics with special photoelectromagnetic properties also have a wide application prospects in the fields of sensors, electronic devices and communication technology.
In short, metallized ceramics, as a new material with excellent properties, will play an increasingly important role in the future field of science and technology and industry. With the continuous progress of the preparation process and technology, it is believed that the application prospect of metallated ceramics will be broader. In order to further promote the application of metallized ceramics, in addition to continuously improving the preparation process and technology, we also need to strengthen the research on its basic theories. For example, to gain insight into the relationship between the microstructure and properties of metallated ceramics, and the interaction mechanism of metals and ceramics at the interface. These basic studies will help to better design the composition and preparation process of metallized ceramics to obtain better performance and wider applications.
In addition, with the continuous progress of science and technology, the application field of metallized ceramics is also expanding. For example, in new energy fields, metallized ceramics can be used for efficient energy conversion and memory devices; in biomedicine, and for biomaterials and medical devices. These emerging application fields provide new opportunities and challenges for the development of metallized ceramics.
In order to seize these opportunities and address the challenges, interdisciplinary cooperation and communication need to be strengthened. We can work together with experts in different fields to discuss the potential and possibilities of metallized ceramics in different application fields, and to carry out joint research projects. This interdisciplinary collaboration will help accelerate the innovation and application of metallized ceramics, making it an important pillar of the future technological and industrial fields.
In short, as a new material, with broad application prospect, is gradually becoming a research hotspot in the field of science and technology and industry. Through the continuous improvement of the preparation process and technology, strengthening the basic research, expanding the application field and strengthening the interdisciplinary cooperation, it is believed that the metallized ceramics will play a more important role in the future development and make greater contribution to the progress of human society. In addition to the above-mentioned improved preparation process, strengthening basic research, expanding application fields and interdisciplinary cooperation, the development of metallized ceramics also needs to pay attention to the following aspects:
