Production Method of Silicon Nanoparticles Nano Si Pulse:

Physical method

The physical method is standard for preparing nano silicon, including mechanical ball milling, laser pulse, and vacuum evaporation methods.

Mechanical ball milling method

The mechanical ball milling method is a method of ball milling of silicon powder through a ball mill. In the ball milling process, the silicon powder is gradually refined to the nanometer level after a long time of ball milling. The advantages of this method are a simple preparation process and low cost. Still, the disadvantage is that the ball milling time is long, and it is challenging to obtain high-purity nanosilicon.

Laser pulse method

The laser pulse method rapidly heats silicon materials by a laser pulse. Under the laser pulse, the silicon material quickly melts and forms nanoscalenanoscale droplets, which are then cooled and solidified into nanosilicon. The advantages of this method are short preparation time and high purity, but the disadvantages are high equipment cost and brutal to large-scale production.

Vacuum evaporation method

Vacuum evaporation is a method of evaporating silicon materials by heating in a vacuum environment. During evaporation, the silicon material gradually vaporizes and forms nano-sized particles, condensing into nano-sized silicon. The advantages of this method are high purity and uniform particle size, but the disadvantages are high equipment cost and low production efficiency.

Chemical law

The chemical method is a standard method for preparing nano silicon, including chemical vapor deposition, solution method, etc.

Chemical vapor deposition

Chemical vapor deposition (CVD) is a method of deposition of nanometer silicon film on silicon substrate by chemical reaction. During the deposition process, the silicon substrate reacts chemically with silane or dichlorosilane in the vapor phase to form a nanoscalenanoscale silicon film. The advantages of this method are high purity and good controllability, but the disadvantages are high equipment cost and low production efficiency.

Solution method

The solution method is a method of synthesizing nano-sized silicon particles in solution. The silicon precursor is dissolved in an organic solvent in the synthesis process. Then, the silicon particles at the nanoscale nanoscale nanoscale are gradually formed by controlling the reaction conditions (such as temperature, pH value, etc.). The advantages of this method are a simple preparation process and low cost, but the disadvantage is that it is challenging to obtain high-purity nanosilicon.

Biological law

The biological method is a method of synthesizing nano-sized silicon particles using biomolecular templates. In this method, biomolecules (such as proteins, polysaccharides, etc.) are used as templates, and by controlling the reaction conditions of the template with the silicon precursor, nanoscalenanoscale silicon particles are gradually formed. The advantage of this method is that the preparation process is simple and environmentally friendly. Still, the disadvantage is that it is difficult to control the size and shape of particles.
