This is a market dataset, representing the consumption market of the region. The dataset includes transport from the gate to the point of consumption, and transport services are calculated based on the transport situation of this product in the region. nano-Si can be used to produce polysilicon, organosilicon polymer materials, and can also replace nano-carbon powder or graphite as negative electrode material for lithium batteries; this dataset includes the main raw materials, auxiliary materials, energy, atmospheric emissions, and wastes in the production process, while infrastructure such as equipment manufacturing and factory building construction used in production is not included in the dataset boundary; the data inventory is formed by merging data from multiple sources; the production of nano-Si uses the electrothermal process, which means using electric energy as a heat source and carbon as a reducing agent, smelting in a semi-enclosed reduction electric furnace; it includes the main procedures of raw material mixing, electric furnace smelting, refining and casting, final crushing.
