We are committed to take part in creating reliable, cost-effective, and environmentally responsible energy solutions, promoting a shift towards a carbon-neutral and sustainable future.
Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2).
The first industrial uses of crystalline silica were probably related to metallurgical and glass making activities a few thousand years ago. It has continued to support human development throughout history, being a key raw material in the industrial revolution especially in the glass, foundry and ceramics industries and is imperative for the development of the green revolution, notably renewable energy.
Silica contributes to today’s Information Technology revolution and is a primary component of mobile phones and tablets. Nearly all the electronic equipment around us uses semiconductor devices. That includes information devices like smartphones, PCs, tablets, and wearable computers; home appliances such as TVs and air conditioners; and means of transportation from cars to trains.
A silicon wafer is a material essential for manufacturing semiconductors, which are found in all kinds of electronic devices that enrich our lives.
The silica mined as the raw material of a silicon wafer is smelted and refined to polycrystalline silicon of extremely high purity. The raw material is melted in a high – purity quartz crucible in an inert gas atmosphere, and made into a monocrystalline in got using proprietary crystal growing technology.
Demand for semiconductors is seen as likely to continue growing. Among the demand drivers are memory and logic devices for storing and processing huge volumes of data in the IoT and big data era; the various sensors needed for safe driving assistance and self-driving cars; and power management devices necessary for reducing energy consumption.
Photovoltaic solar energy offers humankind a useful instrument to build a globally prosperous, sustainable, and environmentally friendly society. Its recent success as an economically viable source of electricity is founded on, the crystalline silicon solar cell.
