Boron Nitride Application-Crucible

By -

 Boron nitride is an excellent self-lubricating ceramic that can withstand high temperatures and maintain its lubrication capabilities in high vacuum environments.

Usually composed of hexagonal boron nitride (P-BN), it has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dissipation material and high temperature insulation material.
Due to its high thermal and chemical stability, boron nitride crucibles are used in high temperature applications.

Boron Nitride Crucible
They are also used in metal casting because it bonds well to metals, as a sandwich of metal borides or nitrides is formed.
The benefits of using a boron nitride crucible are its low wettability to molten metal, relatively high resistance to thermal shock, and conductivity with low thermal expansion. Another advantage of boron nitride crucibles is their very high operating temperatures and appropriate inert gas protection (temperatures above 3000°C have been recorded).
Boron nitride crucible is used for melting aluminum, zinc and other alloy smelting, replacing graphite crucible.
The boron nitride crucible has strong resistance to thermal shock and will not crack when quenched to 1500 degrees. It will not crack if it is kept in the furnace at 1000 degrees for 20 minutes and taken out to be blown and quenched continuously for hundreds of times.
Note: Boron nitride crucible is easy to absorb moisture and cannot be stored in humid areas. It cannot be washed with water. It can be wiped directly with sandpaper or wiped with alcohol.

What makes the ceramic heating element the core part of a Vaporizer?

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 ...
