Silicon dioxide, with the chemical formula SiO ₂, is one of the most abundant compounds in the Earth's crust, widely present in substances such as sand, quartz, and crystal. This seemingly ordinary substance, processed by human intelligence, has transformed into an indispensable key material in high-tech fields, shining brightly in areas such as semiconductors, fiber optic communication, and photovoltaic power generation.
The cornerstone of the semiconductor industry:

High purity silicon dioxide is a key material for manufacturing semiconductor chips. In the chip manufacturing process, silicon dioxide is used as a gate dielectric layer, shallow trench isolation layer, etc. Its purity directly affects the performance and yield of the chip. With the continuous development of semiconductor technology, the demand for purity of silicon dioxide is also increasing. Currently, the most advanced chip manufacturing process requires the use of electronic grade silicon dioxide with a purity of 99.99999999%.
The 'highway' of fiber optic communication:
Silicon dioxide is the main material for manufacturing optical fiber preforms, which are the raw materials for producing optical fibers. Fiber optic communication has become the backbone of modern communication networks due to its advantages such as large transmission capacity, low loss, and strong anti-interference ability. It can be said that without silica, there would be no modern high-speed Internet.
The "energy converter" for photovoltaic power generation:
Silicon dioxide is one of the main materials for manufacturing solar panels. In solar panels, silicon dioxide is mainly used to make anti reflective coatings, which can improve the absorption efficiency of sunlight and thus enhance the power generation efficiency of solar panels. With the transformation of the global energy structure and the rapid development of the photovoltaic power generation industry, the demand for silicon dioxide will continue to grow.
