 AlN Aluminum Nitride Ceramic Crucible

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.


– 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

AlN Aluminum Nitride Ceramic Crucible

Product Description
