The escalating demand for high-purity solar-grade silicon has elevated the significance of trichlorosilane as a pivotal element in semiconductor silicon production. Thus, this investigation utilizes the multiphase particle-in-cell approach to simulate the hydrochlorination process of silicon in the gas–solid spouted system. After the model …

In reality, liquid silicone and silicone rubber production is a fairly straightforward process that can be scaled up and at a relatively low cost on a mass scale. Consequently, it is not surprising that versatile silicone has become one of the most popular mass production elastomers in commercial and industrial applications.

A process called epitaxy (EPI) is used to grow a layer of single crystal silicon from vapor onto a single crystal silicon substrate at high temperatures.

Low-carbon ferromanganese (LC-FeMn) is an essential ingredient for making high-strength low-alloy steel and stainless steel. The conventional industrial-scale silicothermic method for the production of LC-FeMn comprises several energy intensive complex steps consuming about 2000 kWh/ton. We have attempted an improved …

When the trichlorosilane gas has been sufficiently purified, polycrystalline silicon production can begin. The Siemens process is the main method here, and is a form of chemical vapor deposition.

The production of silicon by using iodide process starts with a reaction between unpurified Si and I to form silicon tetraiodide (SiI 4) (Eq. (12)) followed by purification (Eqs.

The printed circuit board (PCB) manufacturing process requires a complex procedure to ensure the performance of the finished product. Though circuit boards can be single, double or multilayered, the fabrication processes used only differ after the first layer's production. Due to differences in the structure of the PCBs, some may require 20 or more steps …
