· KSO4

KSO₄ is a potassium sulfate-based ceramic compound used primarily in specialized industrial and chemical applications. It finds use in fertilizer production, glass manufacturing, and as a component in certain refractory materials where chemical stability and resistance to alkali environments are required. Engineers select this material for applications demanding thermal stability and resistance to corrosive chemical environments, though its use is typically limited to non-structural roles due to the availability of higher-performance ceramic alternatives.
