Silicon metal blocks and silicon metal briquette are two common forms of silicon metal alloys, which have different compositions and uses.
Silicon metal blocks usually contain higher silicon content (over 98%) and lower carbon, aluminum, and iron content, and are commonly used as a raw material in the production of various silicon-based products, including semiconductors, solar cells, and aluminum alloys. Silicon metal blocks are also added to steel to improve its strength and durability.
On the other hand, silicon metal briquette typically contain a lower silicon content (around 65-70%) and higher levels of carbon, aluminum, and iron, compared to silicon metal blocks. Silicon metal briquette are mainly used as a reducing agent in the production of low-carbon ferroalloys, such as ferrosilicon, which are used in the foundry industry for casting and molding.
In summary, silicon metal blocks are used primarily in the production of high-tech products, while silicon metal briquette are mainly used in the manufacture of ferroalloys for the foundry industry.
