FAQ
Q: What is the definition of a quartz boat carrier?
A: A quartz boat carrier (also called a quartz wafer boat holder) is a high-purity quartz component designed to hold and position quartz wafer boats during high-temperature semiconductor and photovoltaic processing. These supports provide stable positioning within diffusion furnaces and other thermal processing equipment.
Q: What is the maximum temperature for quartz boat carriers?
A: TOQUARTZ® quartz boat carriers can withstand continuous operating temperatures up to 1100°C for long-term applications and up to 1350°C for short-term processing cycles. The precise temperature rating depends on specific designs and applications. Above these temperatures, the quartz may begin to soften or deform.
Q: How do quartz boat carrier prices compare to alternatives?
A: Quartz boat carrier prices typically range from $30-150 per unit depending on dimensions, complexity, and order quantity. While ceramic alternatives may have lower initial costs, quartz carriers offer superior temperature stability, chemical resistance, and longer service life, resulting in better long-term value and lower production interruption risk.
Q: Can quartz boat carrier factory services include custom design assistance?
A: Yes, TOQUARTZ® provides comprehensive design engineering support for custom quartz boat supports. Our technical team works directly with clients to develop solutions optimized for specific applications, including CAD drawing assistance, material selection, and design optimization for thermal stability and mechanical strength.
