Description of Iron Disilicide FeSi2 Powder :

Physical property

Iron silicide is a gray or black metallic material with a high density of 7.82 g/cm³. Its melting point is also very high, reaching 1423 ° C, which allows iron silicide to maintain its stability at high temperatures. In addition, iron silicide has high hardness and good wear resistance.

Chemical properties

Iron silicide is chemically stable and has good oxidation resistance and corrosion resistance. At room temperature, iron silicide cannot readily react with oxygen, water vapor, and other substances in the air. Iron silicide can maintain its chemical stability even at high temperatures. However, at high temperatures, iron silicide may react with some active metals to form silicides, affecting its corrosion resistance.

Mechanical properties

Iron silicide has excellent mechanical properties. In addition, iron silicide also has good plasticity and toughness, which can be deep processing and cold processing. These properties give iron silicide a significant advantage in manufacturing complex shapes and high-performance parts.

High-temperature stability

Iron silicide can maintain its physical and chemical stability at high temperatures. At high temperatures, the crystal structure of ferrosilicide does not change, and there is no apparent grain growth phenomenon.

Production Method of Iron Disilicide FeSi2 Powder ：

Smelting process

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

The powder of iron 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 iron and silicon melt and mix well.

Adjust the melt temperature and composition to conform to the phase diagram of iron 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 ferrosilicide material.

The advantages of the smelting method are a simple preparation process, low cost, and suitable for large-scale production. However, the smelting method has high requirements for the purity and quality of raw materials. Otherwise, it will affect the performance of iron silicide. At the same time, impurities are easily mixed in the smelting process, which requires post-treatment measures such as refining and purification.

Mechanical alloying method

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

The powder of iron 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 ferrosilicide 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 ferrite or silicate as raw material and prepared by controlling reaction conditions. The specific steps are as follows:

Dissolve the ferrite or silicate in the organic solvent, and add an appropriate catalyst and reaction medium.

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

After washing, drying, and screening the generated solid material, the ferrosilicide 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.
