Silicon dioxide, also known as silica, is a compound composed of silicon and oxygen atoms. Its melting point is a crucial property that determines its behavior under elevated temperatures. When subjected to heat, silicon dioxide exhibits a melting point of 1723 degrees Celsius (3133 degrees Fahrenheit) under ambient pressure. This high melting point makes silicon dioxide an excellent refractory material, resistant to deformation and softening at high temperatures.
