Boron Nitride Ceramic (h-BN)

Description

1. Product Overview
Boron Nitride Ceramic (hexagonal polymorph, h-BN) is a high-performance advanced ceramic engineered for extreme thermal management and electrical isolation in demanding industrial environments. Its primary industrial use lies in high-temperature processing equipment, semiconductor manufacturing, and molten metal handling, where conventional ceramics fail due to thermal shock or chemical attack. The key value proposition is a unique combination of high thermal conductivity (comparable to some metals) coupled with exceptional dielectric strength and machinability. Strategically, h-BN is critical for industries transitioning to higher energy densities and temperatures—such as EV battery production and aerospace—where it enables safer, more efficient system design.

2. Key Specifications & Technical Characteristics

• Chemical composition: Hexagonal Boron Nitride (h-BN) with trace sintering aids (e.g., B₂O₃, CaO)

• Purity level: Standard grade 98.5%; High-purity grade 99.7% (low oxygen, low carbon)

• Physical characteristics:

  • Form: Solid rods, plates, custom-machined parts, or fine powder (1–10 µm)

  • Color: White to off-white

  • Particle size (powder): D50 = 3–8 µm (adjustable)

  • Density: 1.9 – 2.1 g/cm³ (theoretical density 2.28 g/cm³)

  • Hardness: Mohs 2 (easily machinable with carbide tools)

  • Max use temperature (inert atmosphere): 2,100°C (in air: 850°C)

• Packaging options: Anti-static sealed PE bags + reinforced cardboard drums; vacuum-sealed aluminum foil bags for powder

• Shelf life: 36 months in original unopened packaging (store < 60% RH, 5–30°C)

3. Core Industrial Applications

• Primary industries: Semiconductor & electronics, metallurgy (non-ferrous), aerospace, nuclear power, EV battery manufacturing

• Specific use cases:

  • Semiconductor: Plasma etch chamber components, wafer handling (low particle generation)

  • Metallurgy: Crucibles and nozzles for aluminum, magnesium, and zinc die-casting (non-wetting, no reaction)

  • Aerospace: High-temperature electrical insulators for jet engine sensors

  • EV batteries: Heat spreader insulators for power modules (reduces hotspots)

• Why better than alternatives:

  • vs. Alumina: 3x higher thermal shock resistance; machinable to tight tolerances

  • vs. Graphite: Electrically insulating (no short-circuit risk), non-wetting to molten metals

  • vs. Aluminum Nitride: Easier machining → 50% lower tooling cost for complex shapes

• Efficiency advantage: Reduces downtime for part replacement by 4–6x in continuous molten metal contact vs. fused silica.
