What is aluminum nitride ceramics

By -


Aluminum nitride (AIN) is known for its high thermal conductivity and excellent electrical insulation properties. It is a common ceramic material used in a variety of electrical devices. In addition to its coefficient of thermal expansion and electrical insulation capabilities, aluminum nitride ceramics are resistant to most molten metals, such as copper, lithium and aluminum.

AIN ceramics
Properties of aluminum nitride ceramics:
Aluminum nitride has a variety of properties that make it suitable for a variety of industrial applications:
High thermal conductivity (above 170 W/mK). This is close to the value of BeO and SiC and more than five times that of aluminum oxide (Al2O3).
Its coefficient of thermal expansion is 4.5 *10-6°C, the same as that of silicon (3.5-4 *10-6°C).
It has good light transmission properties
It is not toxic.
Good electrical conductivity. Aluminum nitride’s electrical properties include its dielectric constant, dielectric loss, bulk resistivity and dielectric strength – all of which make it an excellent insulating material.
Good mechanical properties: Aluminum’s mechanical properties are also responsible for its widespread use in industrial processes. It has a higher flexural strength than aluminum oxide (Al2O3) and beryllium oxide (BeO) ceramics.

Wide range of aluminum nitride ceramics:
Aluminum nitride ceramics are used in many applications because of their good properties, including high thermal conductivity, low dielectric constant and dielectric loss, high dielectric strength, and significant resistance to plasma erosion.
Chip heat dissipation and support
Aluminum nitride ceramic substrates (ceramic trays) in semiconductor devices
Aluminum nitride etch shielding
Aluminum nitride evaporation boats for OLEDs
Also used for packaging of various electronic components

Source: https://www.innovacera.com/news/ceramic-heater-coil-for-vaporizer.html Not every dry herb vaporizers are the same! Especially those used ceramic heating element. The ceramic heating element is a safety and healthiest option for dry herb vaporizers, so every vaper is preferred to choose those vaporizers that carry ceramic heating element. The proponents believe that the heating element is the core of the vaporizer and primarily dictates the experience of the taste. Let's more specific, when a vaper burns tobacco, marijuana, or hemp during traditional smoking to release the active component, whatever it's nicotine, CBD, or THC, they inhale the smoke. We all know that's not good for health. Rather than burning, Vaporizer heats the liquid, wax or even dry herb to release a vapour, and a vaper inhales the vapour without any damage to their lungs or throat. And why the ceramic heating element is becoming the core part of the vaporizer? It's mainly because: 1. Ceramic ...
