Boron Nitride Aerosol Spray
Boron nitride is a chemical compound that is known for its high thermal and electrical resistance. It is also non-toxic for humans and is mostly available in the form of white powder or colorless crystals. Thus, it is also called white grapheme or inorganic graphite, due to its structural resemblance with the carbon allotropes. Now, boron nitride aerosol spray is available in the market, which is more convenient to use for lubrication of surfaces. This spray contains boron nitride powder dispersed in liquid acetone, along with a little amount of binder.
How to use Boron nitride as an aerosol spray?
Firstly, the surfaces should be thoroughly cleaned, which are supposed to be coated with boron nitride. All the foreign particles should be eliminated from these surfaces, to enable uniform coating of this chemical. Then the aerosol spray should be shaken well, to mix the dispersed boron nitride particles uniformly within the liquid. The spray bottle should be held around 70 cm away from the surface to be coated. Now, this bottle should be moved slowly while pressing its nozzle to release the boron nitride mixture evenly over the surface. The coating needs to be a thin layer, as thick layers may crack and flake off under pressure. Several thin layers of coating are recommended for achieving the desired results. However, each layer should be dried before spraying the next layer of coating.
Uses of Boron nitride in an aerosol spray
Boron nitride is a lubricant that can be used at very high temperatures, up to 1950 degrees C. Thus, it can be used in coating gasket wires, foundry moulds, and many machines that work only under high temperatures. This coating is used for protecting tools that are used for casting molten metals, like lead, magnesium, zinc, and aluminum, to solidify into a mold. Boron nitride is used as an additive to improve the thermal conductivity of resins and silicone, which are needed in manufacturing electrical appliances and paints. Boron nitride behaves as a semiconductor at high temperatures while it turns into an insulator at normal room temperature.
An aerosol spray is easy to use for all and thus, boron nitride is best used in the form of this spray for different commercial purposes.
