Recycled Boron Nitride – HeBoFill® BL-PC 060

A technical recycled high quality powder which is produced during the machining of sintered boron nitride components. Composition and particle size distribution are adjusted by means of targeted processing. Due to the raw materials used, this powder also contains admixtures of valuable refractory zirconium and silicon compounds. Boron nitride is resistant up to 900°C in air and up to 2000°C under vacuum/inert conditions. As such is a low cost alternative for technical applications, with good lubricating and release properties compared to other ceramic powders. It is composed of approximately 70% BN, 15% Zirconia, 10% Silica compounds, 1% soluble Borates and 4% of other ceramic compounds. With a Specific surface Area (BET) of 6-9 m²/g and a median particle size (D₅₀) of ~6µm. Due to its composition the powder is available in light grey colour. Available packing units are 1Kg plastic bags and 10Kg hard paper drums. Due to the recycling process the annual quantity is limited to approx. 5-6 t/year. Most common applications include, filler in coatings to improve for technical applications, as base material for high-quality realease coatings or as filler for refractory products.
