Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. Silicon carbide is industrially used mainly as an abrasive (such as grinding wheels and grinding powder) and refractory material, and is also used for deoxidation and carburization in metallurgy; in the electronics field it serves as a third-generation semiconductor material for the production of high-temperature, high-voltage devices; in the new energy and automotive fields it is used to improve power conversion efficiency; this dataset includes the main raw and auxiliary materials, energy, waste gas and waste of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the production activity of this product includes batching and mixing, furnace charging, smelting, cooling, furnace discharging and grading, granulation, micronization and other process steps, and artificial (high-purity) graphite is a by-product of the production process, allocated based on physical relationship (mass).
Activity Description
The production activities of this product include batching and mixing, furnace loading, smelting, cooling, furnace classification, granulation, micronization and other processes.
Process Description
Silicon carbide chemical formula SiC, CAS number 409-21-2, is a light green to black crystal. It has high hardness at room temperature, high temperature resistance, corrosion resistance, and relatively stable chemical properties. It has high melting point, good thermal conductivity, adjustable resistivity, and does not react with most chemicals under normal conditions. In industry, it is mainly used as abrasives (such as grinding wheels, grinding powder), refractory materials, and also used for deoxidation and carburization in metallurgy; in the electronic field, it is used as a third-generation semiconductor material to produce high-temperature and high-voltage devices; in the new energy and automotive fields, it is used to improve power conversion efficiency.
