High Grade Silicon Metal
Main Introduction To Metallic Silicon
Metallic silicon is an important raw material used in the production of silicon-containing alloys and the electronics industry. The traditional production method is to use carbonaceous as a reducing agent to reduce silica to silicon in a submerged furnace.
Silicon In Cast Iron
Petroleum coke is a well-known reducing agent with low impurity content. It can be used to obtain high-quality metallic silicon without refining outside the furnace. Therefore, some manufacturers also use petroleum coke plus wood chips or wood blocks to produce metallic silicon. However, due to the strong graphitization properties of petroleum coke, it quickly graphitizes at the smelting temperature of the submerged arc furnace, causing the furnace bottom to rise, which not only wastes a large amount of electric energy, but also prevents normal production.
Introduction To Other Silicon Alloy Products
Silicon can be alloyed with other metals to enhance its metallic properties. Alloys made of silicon mainly include: silicon-aluminum alloy, silicon-copper alloy, ferrosilicon alloy, silicon-manganese alloy, etc.
Metallic Silicon
The presence of silicon element in silicon-aluminum alloy can improve the fluidity of the alloy, reduce the tendency of hot cracking, reduce porosity, and improve air tightness. This type of alloy has good corrosion resistance and moderate machinability, has medium strength and hardness, and has low plasticity. It is used to manufacture castings with low and medium strength and complex shapes, such as cover plates, motor casings, and brackets. etc., also used as brazing solder.

Special Uses Of Silicon Metal Blocks In Other Areas
Silicon plays a great role in improving plant resistance to abiotic and biotic stress. It is a chemical element necessary for plants to resist stress and regulate the relationship between plants and other organisms. For example, silicon can increase the hardness of plant stems, and silicon can improve plant resistance to drought, salt stress, ultraviolet radiation, and pests and diseases. Silicon can improve the resistance of rice to the rice leaf roller. After applying silicon, the rice's defense response to pest feeding is rapidly improved. Silicon plays a guarding role in plant defense.
