Hexagonal Boron Nitride

Hexagonal Boron Nitride which commonly referred to other name “white graphite”, it is multi-layers pure white powder which none wet to Aluminum, Zinc, copper melt. Hexagonal Boron Nitride is a none toxic, excellent lubricate at high temperature than graphite which widely used in commonly industry. Adtech boron nitride coating is used for Aluminum metallurgy, easy brush to launder, billet rings, casting tables, blender, it will be none stick. Easy to brush and easy to clean.

The unique combination of thermal, mechanical, electrical and physical properties makes Boron Nitride a unique material for hot metal processing and refractory applications. Boron Nitride, a truly versatile material, is commonly used in powder form as solid lubricants or mold release agents, in liquid coating form as liquid release agents, and in solid form as hot-presses intricately shaped solid components for furnace construction, crucibles, and insulators.

The key properties that contribute to Boron Adtech versatility in metal processing applications are:

Extreme temperature resistance and thermal shock resistance
High oxidation resistance up to 850°C
Low coefficient of friction – outstanding lubrication properties
Corrosion resistance – not wet by most molten metals or slag
Chemically stable, pure and highly inert even at high temperatures

Boron Nitride Coatings are entirely inorganic, composed of boron nitride powder and a high-temperature bond phase. Supplied in a liquid form suitable for brushing, Combat Boron Nitride Coatings can be diluted with water to spraying and dipping consistencies and applied to a variety of porous and non-porous materials including graphite, metals, ceramics and organics.

Combat BN Coatings can be used up to 1372°C (2500°F) in a reducing/inert atmosphere and 850°C (1562°F) in an oxidizing atmosphere, and will retain many of the properties of Boron Nitride such as:

Non-wet by most molten metals, salts, fluxes and slags
Resistant to molten metal corrosion and light metal drosses
Excellent parting plane / very lubricious
Helps in removal of solidified metals
