Step 1: Understanding the Question:
The question asks to identify the chemical compound produced commercially using the specific industrial method known as the Acheson process.
Step 2: Detailed Explanation:
Acheson Process: Developed by Edward Goodrich Acheson, this is an industrial electrothermal process used to synthesize Silicon Carbide (SiC) and synthetic graphite.
In this process, a mixture of high-purity silica sand ($SiO_2$) and carbon (usually petroleum coke) is heated in a large electric resistance furnace.
The chemical reaction is: \[ SiO_2 + 3C \rightarrow SiC + 2CO \]
The core of the furnace reaches extremely high temperatures (above $2500^{\circ}C$), where SiC crystals form.
Other Materials:
Alumina ($Al_2O_3$): Produced via the Bayer process from Bauxite.
Zirconia ($ZrO_2$): Produced through chemical processing of Zircon sand or baddeleyite.
Step 3: Final Answer:
The Acheson process is primarily used to prepare Silicon Carbide (SiC).
