Boron nitride powder

fillerfor plastics

Overview
Innovacera's boron nitride (BN) powder is synthesized by high-temperature reaction of imported boric acid and melamine; select grades use alternative high-quality precursors. The powders provide low impurity levels, high chemical purity, controlled crystallinity and adjustable particle size distribution. Available morphologies include single-crystal platelet powders and nanoscale spherical agglomerates suited for industrial applications.

Available grades / product types

• Ceramic grade
• Thermal conductivity grade
• Cosmetic grade
• Electronic grade
• Lubrication grade
• Custom grades available on request

Forms and particle sizes

• Single-crystal platelet powders: 0.5 μm – 100 μm
• Nanoscale spherical agglomerates

Key features

• High thermal resistance and thermal conductivity
• Low coefficient of thermal expansion
• Excellent thermal shock resistance
• High-temperature electrical insulation
• Superior chemical corrosion resistance
• Low friction coefficient with self-lubricating behavior

Applications
Because BN combines high thermal conductivity with electrical insulation, these powders are used in electronics (thermal interface materials, semiconductor package filling, LED cooling), metal smelting and casting, specialty lubricants, glass and thermoplastics processing, and in large-scale industrial R&D and production.
