Boron Nitride is a high-temperature ceramic that has a structure similar to graphite. Our portfolio of hot-pressed solid materials includes pure Hexagonal Boron Nitride as well as composites suitable for applications requiring excellent thermal properties combined with electrical isolation.
Easy machinability and fast availability make Boron Nitride an outstanding choice for prototypes to large quantities requiring its unique properties.
| Typical Grades |
BN997 (99.7%); BN993 (99.3%); ALBN (Al2O3-BN); SCBN (SiC-BN); ZRBN (ZrO2-BN); ANBN (AlN-BN); SNBN (Si3N4-BN) |
| Typical Properties | Low density Low thermal expansion Good thermal shock resistance Low dielectric constant and loss tangent Excellent machinability Chemically inert Corrosion resistant Non-wetting by most molten metals Extremely high working temperature |
| Typical Applications | High-temperature furnace setter plates Molten glass and metal crucibles High-temperature and high-voltage electrical insulators Fittings and the lining of the plasma chamber Nonferrous metal and alloy nozzles Thermocouple protection tubes and sheath Boron doping wafers in silicon semiconductor processing Sputtering targets Break rings for horizontal casters |

Q: What is your minimum order quantity (MOQ)?
A: Our minimum order quantity (MOQ) depends on many factors such as product, material, dimensions, etc.
Q: Do you provide free samples?
A: Yes, we are pleased to provide a free sample for your initial evaluation of our materials if we have the sample in stock and if its cost is bearable to us.
Q: Do you accept a trial order before a bulk purchase?
A: Yes, we welcome your trial order to verify our quality before your bulk purchase.
Q: What is your production time?
A: Our production time depends on materials, production methods, tolerances, quantity, etc. Normally, it takes 15-20 days if we have stock material, and it takes 30-40 days if we don't. Please share your specific requirements with us, and we will quote the fastest production time.
Q: What are your payment terms?
A: Our payment terms are T/T, L/C, and PayPal.
Q: What packaging do you use to ensure ceramics are safe?
A: We pack the ceramic products tidily with foam protection inside the carton, plastic box, and wooden box.
Q: Do you accept custom orders?
A: Of course, most of our orders are custom products.
Q: Would you provide an inspection report and material test certificate for our order?
A: Yes, we can provide these documents upon request.
