Description of Copper Silicide Cu5Si Powder :

Physical property

Copper silicide is a dark blue metal material with a density of 8.66 g/cm³, and a melting point of 1365 ° C. Copper silicide has high hardness and corrosion resistance. In addition, copper silicide is also a good conductor, with good electrical and thermal conductivity.

Chemical properties

Copper silicide has stable chemical properties and is not easy to react with oxygen, water vapor, and other substances in the air at room temperature. However, in a temperature environment, copper silicide will react with oxygen to produce copper oxide; the reaction equation is CuSi + O2 → CuO + SiO2. In addition, copper silicide will react with water vapor to produce hydrogen and silicon dioxide at high temperatures, and the reaction equation is CuSi + 2H2O → H2 + SiO2 + Cu.

Mechanical properties

Copper silicide has excellent mechanical properties, and its tensile strength, yield strength, and hardness are higher than those of conventional copper alloys. In addition, copper silicide also has good plasticity and toughness and can be used in deep processing and cold processing. In high-temperature environments, the mechanical properties of copper silicide can still maintain a high level, which means it can be widely used in high-temperature environments.

High-temperature stability

Copper silicide has excellent high-temperature stability and is difficult to change in a high-temperature environment. At higher temperatures, the crystal structure of copper silicide is not easy to change, and there is no apparent grain growth phenomenon. These properties allow copper silicide to be suitable for manufacturing parts at high temperatures.

Smelting process

The smelting method is a standard method for preparing copper silicide, formed by melting and cooling a mixture of copper and silicon at high temperatures. The specific steps are as follows:

The powder of copper and silicon is mixed according to a particular proportion, and an appropriate amount of flux is added, such as KCl, NaCl, etc.

Heat the mixture to a high temperature so the copper and silicon melt and mix well.

Adjust the melt temperature and composition to conform to the phase diagram of copper silicide, and keep the melt at a high temperature for a period to complete the alloying process.

The alloy melt is cooled and crystallized to obtain the copper silicide material.

The advantages of the smelting method are a simple preparation process, low cost, and suitable for large-scale production. However, because the smelting method requires a high-temperature environment, the purity and quality of the raw material need to be high; otherwise, it will affect the performance of copper silicide. In addition, it is easy to mix impurities in the smelting process, such as oxygen, nitrogen, and other elements, so post-treatment measures such as refining and purification are required.

Mechanical alloying method

Mechanical alloying is made by mixing copper and silicon powders and sintering them at high temperatures. The specific steps are as follows:

The powder of copper and silicon is mixed according to a particular proportion, and an appropriate amount of ball milling media is added, such as alumina balls.

In a ball mill, the mixed powder is ball-milled so that it fully contacts and collides to complete the alloying process.

The mixed powder, after ball milling, was sintered at high temperatures to densify and grow grain.

After crushing, grinding, and screening the sintered material, the copper silicide material was obtained.

The advantage of mechanical alloying is that raw materials with lower purity can be used, resulting in alloys with higher purity and without mixing in impurity elements. In addition, the mechanical alloying method can control the grain size and properties by controlling parameters such as milling time and temperature. However, the production efficiency of the automated alloying method is low, the manufacturing cost is high, and the use of a large number of ball milling media is complex to achieve large-scale production.

Chemical synthesis

The chemical synthesis method is based on cuprate and silane as raw materials and prepared by controlling reaction conditions. The specific steps are as follows:

Cuprate and silane were dissolved in the organic solvent, and the appropriate amount of catalyst and reaction medium was added.

The mixed solution is heated and stirred so that it reacts and produces a copper silicide material.

After washing, drying, and screening the generated solid material, the copper silicide material was obtained.

The advantage of chemical synthesis is that raw materials with higher purity can be used, and the obtained alloy has higher purity and will not be mixed with impurity elements. In addition, the chemical synthesis method can control the grain size and properties by controlling the reaction conditions. However, the production cost of chemical synthesis is high, and many chemical reagents, such as organic solvents and catalysts, need to be used, which has a more significant impact on the environment.
