EQ-500
Fused quartz material produced via vacuum melting, characterized by an extremely low hydroxyl content, can be processed into transparent quartz wafers, square blanks, and other forms, primarily serving as a key material for infrared optical windows in defense‑related and other specialized applications, as well as for semiconductor quartz components. It can also be drawn into tubing and other shapes, making it suitable for the electronics industry and other sectors with stringent requirements for low hydroxyl levels.
