Boron Nitride Ceramics (BN) are advanced ceramic materials composed of boron and nitrogen, typically in a hexagonal crystal structure (hexagonal boron nitride, hBN) similar to graphite. Common processing methods include hot pressing and chemical vapor deposition (CVD). Other fabrication techniques, such as hot isostatic pressing (HIP) and spark plasma sintering (SPS), can also be used. The material’s properties can be tailored by adjusting parameters like pressure, temperature, and sintering time.

Hot-pressed hBN products exhibit a range of desirable properties, including good thermal conductivity, electrical insulation, high-temperature stability (up to 2000°C in vacuum or inert atmospheres), low friction coefficient, thermal shock resistance, chemical inertness, and low density. These characteristics make hBN widely used in the processing of high-performance materials, such as glass and metal forming, where it often serves as a refractory or functional structural component.

BN ceramics are easy to machine. Even complex geometries can be processed using conventional methods such as sawing, turning, drilling, milling, or ultrasonic-assisted machining. WEIERT CERAMICS is equipped with advanced CNC machining facilities, supporting both rapid prototyping and large-scale production. With our extensive experience and well-developed ceramic machining processes, we are able to maintain low defect rates—helping customers reduce both purchasing and trial-and-error costs.

Typical applications include:

• Semiconductor and high-temperature processing equipment
• Components for glass and metal forming in metallurgical industries
