1. What is the purity level of the alumina in the ceramic rings?
Our ceramic rings are expertly crafted from high-purity alumina (Al2O3) with a purity level ranging between 95% and 99%.
These versatile ceramic rings are primarily used as insulation supports in demanding high-temperature and high-voltage applications, including:
Dimensions and tolerances can be tailored to your specific requirements. Please provide detailed specifications or drawings for an accurate quotation.
Our 95-99% alumina ceramic rings boast a typical thermal conductivity of ≥25 W/m·K, with slight variations depending on purity and processing methods.
These alumina ceramic rings provide strong dielectric strength, typically ≥10 kV/mm, ideal for high-voltage insulation applications.
Absolutely, our ceramic rings exhibit high mechanical strength, with a compressive strength of ≥2000 MPa and a flexural strength of ≥300 MPa.
The coefficient of thermal expansion for our alumina ceramic rings typically ranges from 6-8 x 10-6/°C.
