Si Powder
1. The particles of atomized iron powder are smaller and the particles of reduced iron powder are slightly larger.
2. The purity will be marked, depending on the type purchased;
3. They are all iron powder. They will generate the same heat when fully reacted, but the atomized iron powder particles are smaller and easier to fully react.
4. If it is distilled water, it will not happen, but if the water is impure, an electrochemical reaction will occur, and the heat will be negligible. Of course, if you specially prepare an electrolyte solution, it can also generate a large amount of heat in a short period of time. Theoretically, it can reach about 60°C.
Silicon (Metal) Powder Extra Pure
Reduced iron powder is generally produced by reducing iron tetroxide in a hydrogen gas flow or a carbon monoxide gas flow under high heat conditions. The main component is elemental iron with a loose structure. Since the reduced iron powder itself is in powder form and its microstructure is very loose, its surface is extremely large. It is often used as a high-quality reducing agent in chemical production and laboratory operations.
Silicon Powder 325 Mesh
Reduced iron powder: complex particle shape, good powder molding performance, easy to manufacture complex-shaped or thin-walled parts; good powder sintering activity; low powder purity and compressibility. It can manufacture a large number of low- and medium-density iron-based powder metallurgy parts of high quality and low price.
Atomized iron powder: The high-pressure water atomization method is used to produce coarse alloy powder. The crude gold is first melted in a furnace. The melted gold liquid must be overheated by about 50 degrees and then injected into the tundish. Before the gold liquid is injected, start the high-pressure water pump and let the high-pressure water atomization device start the workpiece. The gold liquid in the tundish bag passes through the beam and enters the atomizer through the leaky nozzle at the bottom of the bag. The atomizer is the key equipment for producing coarse gold alloy powder with high-pressure water mist. The quality of the atomizer is related to the crushing efficiency of the metal powder. Under the action of high-pressure water from the atomizer, the gold liquid is continuously broken into fine droplets, which fall into the cooling liquid in the device, and the liquid solidifies into alloy powder.
