Production Method of Silicon Aluminum Alloy Powder Si-Al:

Smelting process

Smelting is one of the most commonly used methods in the production of silicon aluminum alloy. The method is to mix silicon and aluminum, two metals according to a certain proportion, and melt at high temperatures to form silicon aluminum alloy melt. Then, the melt is treated by pouring, cooling, crushing, grinding, etc., to obtain silicon aluminum alloy powder or particles. The advantage of the smelting method is that the production process is simple, mature, and can be large-scale production, but the production process needs to consume a lot of energy, and the production cost is high.

Mechanical alloying method

Mechanical alloying is a method of mixing two metal powders, silicon, and aluminum, together by the action of mechanical energy. The method is to mix the silicon and aluminum two metal powders according to a certain proportion through the ball mill, vibration mill, and other mechanical devices for a long time grinding so that the silicon and aluminum two metal atoms are fully mixed to form silicon aluminum alloy powder or particles. The advantage of the mechanical alloying method is that the production cost is low, but the production cycle is long. A lot of mechanical equipment is required.

Jet co-sinking method

The jet co-deposition method is a method of atomizing by spraying the gas or liquid medium in the fluidized bed after mixing the two metal elements of silicon and aluminum in a certain proportion. The method is to mix the two metal elements of silicon and aluminum in a certain proportion and send them into a jet-fluidized bed, atomize the metal droplets into tiny particles through the action of high-speed airflow, and then settle, cool, and cure them in the fluidized bed to obtain silicon aluminum alloy powder or particles. The advantages of the jet co-deposition method are high production efficiency and low cost. Still, the requirements for equipment are high, and the injection speed and the mixing ratio of metal elements need to be controlled.

Chemical vapor deposition method

Chemical vapor deposition (CVD) is a method in which silicon and aluminum are deposited on the surface of a matrix by chemical reaction. In this method, the compounds of silicon and aluminum are used as raw materials, and the compounds are converted into silicon aluminum alloy by chemical reaction and then deposited on the surface of the substrate to form a coating or film. The advantage of chemical vapor deposition is that high-purity silicon aluminum alloy coating or film can be obtained. Still, the production cost is high, and the conditions of chemical reaction and deposition thickness need to be controlled.

Vacuum melting method

Vacuum smelting is a method of melting silicon and aluminum, two metal elements, in a vacuum environment. The method is to heat the two metal elements of silicon and aluminum into the crucible to the melting point under a high vacuum environment and then melt, cool, and solidify to obtain silicon aluminum alloy ingots. The advantage of the vacuum melting method is that high-purity silicon aluminum alloy ingot can be obtained. Still, the production cost is high, and the vacuum degree and melting temperature need to be controlled.
