What is the trick to making copper iridium?

In the modern chemical industry, copper iridium, as an important alloy material, is widely used in electronics, catalysis, aerospace and other fields because of its excellent physical and chemical properties. The production of copper iridium is not easy, the process is complex and the requirements for raw materials and equipment are extremely high. In this paper, the knack of making copper iridium will be discussed in detail from three aspects: raw material selection, synthesis process optimization and performance improvement.

1. raw material selection: laying the foundation for high-quality alloys

The first step in making copper iridium is to choose high-quality raw materials. Copper and iridium are the main components of copper-iridium alloy, and their purity directly affects the performance of the final product. High purity copper (purity ≥ 99.99%) and iridium (purity ≥ 99.95%) is a prerequisite for the preparation of high quality copper iridium. When selecting raw materials, priority should be given to reputable suppliers and ensuring that the chemical composition of the material meets industry standards.

The particle size of the raw material is also a key factor. Fine-grained copper and iridium powder are beneficial to improve the uniformity and compactness of the alloy, thereby improving the performance of the final product. Therefore, in the raw material procurement stage, it is recommended to carry out strict quality inspection on the supplier's materials to ensure that they meet the process requirements.

2. synthesis process optimization: master the core technology

The synthesis process of copper iridium is the key link to determine its performance. At present, the commonly used synthesis methods include reduction-recrystallization method, fusion casting method and powder metallurgy method. Among them, the reduction-recrystallization method has become the mainstream process because of its high efficiency and controllability.

In the reduction-recrystallization method, copper and iridium oxides are first mixed in a certain ratio, and then a reduction reaction is carried out at a high temperature to produce a mixture of metallic copper and iridium. Subsequently, the microstructure of the alloy is further optimized by a recrystallization process. In this process, the control of temperature and time is very important. Too high temperature may cause the alloy grain size to be too large, affecting its strength and conductivity; while too low temperature may not achieve sufficient recrystallization, resulting in substandard performance.

The synthesis process in a vacuum environment is also a key point. The vacuum environment can effectively avoid the introduction of impurities, thereby improving the purity of the alloy. In actual operation, it is recommended to use high vacuum equipment and strictly control the atmosphere conditions during the reduction and recrystallization process.

3. performance optimization: improve alloy comprehensive performance

The ultimate goal of making copper iridium is to improve its overall performance to meet the needs of different application scenarios. The performance optimization of copper iridium can be started from the following aspects:

1. Microstructure control: By adjusting the synthesis process parameters (such as temperature, time, etc.), the microstructure of copper iridium can be controlled. For example, by controlling the grain size and distribution, the strength and electrical conductivity of the alloy can be significantly improved.

2. Impurity control: The presence of impurities can seriously affect the performance of copper iridium. In the selection of raw materials and synthesis process, effective impurity control measures should be taken, such as the use of high-purity raw materials, the use of refining technology, etc.

3. Surface treatment: oxidation or contamination of the copper iridium surface will adversely affect its performance. Therefore, after the preparation is completed, it is recommended to surface treat the alloy, such as vacuum packaging or chemical cleaning, to ensure the cleanliness of the surface.

4. Future: Exploring New Production Techniques

With the continuous progress of science and technology, the technology of making copper iridium is also constantly innovating. For example, researchers are exploring the use of nanomaterial technology and green synthesis methods to further improve the performance and preparation efficiency of copper iridium. These new technologies can not only improve the performance of the alloy, but also reduce the impact on the environment, opening up a broader prospect for the application of copper iridium.

Conclusion

The production of copper iridium is a complex and precise process, which requires comprehensive consideration from raw material selection, synthesis process optimization to performance improvement. By mastering these know-how, we can prepare copper iridium alloy with excellent performance to meet the needs of different fields. In the future, with the continuous advancement of technology, the application prospects of copper and iridium will be broader, and its production process will be further optimized to make greater contributions to the development of human society.
