Frequently Asked Questions

Q1: How does the density control contribute to the performance of the alumina ring?
A1: The controlled density of 3.5 g/cm³ ensures that the ring maintains its mechanical integrity under cyclic loads. Consistent density reduces the risk of localized stress concentrations, which can cause premature failure in demanding industrial applications.

Q2: What is the significance of the thermal conductivity value in high-temperature applications?
A2: A thermal conductivity of 25 W/(m·K) allows efficient heat dissipation in applications that experience high temperatures. This property helps in managing thermal gradients within assemblies, ensuring stable performance even under continuous high-temperature conditions.

Q3: How does the high volume resistivity benefit electronic assemblies?
A3: A volume resistivity exceeding 10^14 Ohm·cm provides electrical insulation, reducing the risk of current leakage in high-voltage environments. This makes the ceramic ring suitable for applications where electrical isolation is critical to device safety and performance.
