Product Specifications
--Product Description
Polished Aluminum Nitride (ALN) Ceramic Crucible /Innovacera
The aluminum nitride (AlN) ceramic has high thermal conductivity(5-10 times as the alumina ceramic), low
dielectric constant and dissipation factor, good insulation and excellent mechanical properties, non-toxic,
high thermal resistance, chemical resistance ,and the linear expansion coefficient is similar with Si,which is
widely used in communication components, high power led, power electronic devices and other
fields.Special spec products can be produced upon requests.
PRODUCT PERFORMANCE
- High thermal conductivity, high flexural strength, high temperature
- Good electrical insulation
- Low dielectric constant and loss
- Able to be laser drilled, metallized, plated and brazed
