Boron nitride sheet introduction
QS Advanced Materials (QSAM) provides hot pressed boron nitride (hBN) made by sintering boron nitride powder/flake into a solid material. This produces a material with low wettability for molten metals and some salts. Boron nitride works as the premier high-temperature electrical insulator, handling over 2000°C in a protective atmosphere. We have tested our BN99 grade to operate smoothly at 3500°C gas flow in an inert gas, although long-term use should remain under 2200°C based on survival tests. In a vacuum, it decomposes before melting at 1900°C. With these exceptional properties, boron nitride serves many applications in PVD coatings, high-temperature furnace systems, and semiconductor manufacturing.
Additionally, our machinable boron nitride ceramic allows custom machining into shapes, if the raw material is large enough. Since the BN solid raw material price is high (> $20/in3), customers can estimate pricing for products like sheets based on the amount of BN solid required. We can machine simple shapes like plates, tubes, rods, and disks. Complex geometries are also possible depending on specifications.
With its excellent thermal and electrical insulation even at extreme temperatures, boron nitride ceramic is perfect for high-heat applications needing temperature resistance far surpassing traditional materials. Contact QSAM to learn more about our high-quality hot pressed boron nitride. We offer the right boron nitride material solution for your specific application requirements.
QSAM supplies custom made boron nitride sheets and other machined products in about 2 weeks with $200 MOQ. We are proud to announce that QSAM can provide the largest commercially available boron nitride sheet, with the ability to produce any sheet up to 16" x 16" x 8". We maintain a large inventory of hot press sintered boron nitride and can readily cut it into the desired sheet sizes, enabling rapid delivery to our customers. We also gladly accept custom processing based your drawings. Please click

Hot Pressed BN Sheet Packaging
As a ceramic material, boron nitride sheets are quite fragile in a lot of cases. Our BN sheets are usually hold in plastic bags by vacuum, and protect with heavy foam.
