In the process of my country’s industrial development, the smelting industry has always occupied a large market, and products produced through special processing can meet many aspects of my country’s industrial field. At the same time, it is the smelting raw materials that play a role in improving the performance of smelting products. Here, the editor will introduce to you the metal silicon block material, which plays a decisive role in my country’s industrial field and has a wide range of applications.

The industrial production of silicon blocks requires strict requirements, and it is necessary to ensure that the impurity content is as low as possible. For example, some cast aluminum alloy companies use die-cast aluminum alloys with a silicon content of about 10%. In new energy industries such as solar energy, silicon block materials are also needed. In fact, the impurity components include aluminum, iron, and calcium. We need to effectively handle impurities in different application ranges.

Its properties are similar to silicon, inactive and difficult to combine with oxygen. At the same time, it is also insoluble in inorganic and organic acids.


Pure silicon minerals are quartz or silica. There are two allotropes: one is a dark brown amorphous powder that is active and can burn in air; the other is a stable crystal (crystalline silicon). Industrial silicon blocks are also used as demanding alloying agents and deoxidizers in the smelting of special steels and non-ferrous alloys. Generally, silica and quartz are used in building materials such as glass, and good quartz is used in the manufacture of alloys, metals and single crystals. “Metal silicon” (also known as industrial silicon in my country) is a product name that appeared in the mid-1960s. Its emergence is related to the rise of the semiconductor industry.

Additional products of metal silicon blocks: including silicon powder, edge silicon, black silicon, metal silicon slag, etc. Microsilica powder is also called silica powder, microsilica powder or silica fume. Metallic silicon, which is widely used in the refractory and concrete industries: It is industrially purified elemental silicon and is mainly used to produce organic silicon, high-purity semiconductor materials and alloys prepared for special purposes, etc. If the particle size is too small, although the contact surface of the reducing agent can be increased, which is beneficial to the reduction reaction, the gas generated during the reaction cannot be discharged smoothly, which will slow down the reaction speed. Also known as crystalline silicon or industrial silicon, it is mainly used as an additive for non-ferrous alloys.

Silicon block is an industrially purified element, mainly used to produce organic materials, prepare high-purity semiconductor materials, and prepare alloys for special purposes. Manufacturing high-purity semiconductors: Modern large-scale integrated circuits are almost all made of high-purity metal silicon blocks, and they are also the main raw material for the production of optical fibers. It can be said to be the basic pillar industry of the information age. When the particle size is too large, since it cannot adapt to the furnace stickiness and reaction speed, unreacted silica can easily enter the liquid silicon, resulting in an increase in the amount of slag, difficulty in discharging the furnace, a reduction in the recovery rate of silicon, an increase in energy consumption, and even damage to the furnace. The price rises at the bottom, affecting normal production. With the development of science and technology, the application fields of metallic silicon will be further expanded.
