Features of Aluminum Nitride Ceramic Plate

1. High Thermal Conductivity: Among the most remarkable attributes of AlN ceramic plates is their extraordinary thermal conductivity, which can vary from 170 to 220 W/m · K. This makes them above lots of other porcelains for applications needing reliable warmth dissipation.
2. Exceptional Electric Insulation: Despite their high thermal conductivity, AlN plates maintain outstanding electrical insulation buildings, making them optimal for use in electronic packaging and semiconductor applications where dielectric toughness is critical.
3. Reduced Coefficient of Thermal Growth (CTE): The CTE of light weight aluminum nitride is fairly reduced and carefully matches that of silicon (~ 4.5-5.0 ppm/ ° C). This minimizes thermal mismatch tensions when these products are made use of with each other in digital devices.
4. Chemical Stability: AlN ceramic plates display excellent resistance versus chemical corrosion, consisting of resistance to thaw steels and numerous acids and antacid, improving their durability in rough atmospheres.
5. Mechanical Stamina: They possess sufficient firmness and toughness for numerous commercial applications, although they are fragile and can fracture under effect or extreme anxiety.
6. Density: The thickness of AlN is around 3.26 g/cm ³, contributing to its light-weight nature compared to a few other ceramic products.
7. Pureness: High pureness options are available, with purities typically exceeding 99%, which can improve thermal and electrical buildings.
