Electrical Properties
Fused quartz, with its minimal alkali ions, is the ideal choice for electrical insulation and low-loss dielectric properties. Its remarkable ability to maintain insulation and efficient transmission, even at high temperatures and across various frequencies, highlights its enduring strength and reliability under extreme conditions.
