High Wear Resistance Silicon Nitride Si3N4 GPSN Ceramic Block High Hardness
High hardness and high wear Resistance Silicon Nitride/Si3N4/GPSN Ceramic Block L38*W25*T6.3mm
1 . Descriptions:
Boron carbide (B4C) is one of the world's hardest manufactured materials. Its strong chemical bonds and hard surface minimize wear in rigorous environments.
Boron carbide, in conjunction with other materials also finds use as ballistic armour (including body or personal armour) where the combination of high hardness, high elastic modulus, and low density give the material an exceptionally high specific stopping power to defeat high velocity projectiles.
2 . Advantages
• Low thermal conductivity
• Susceptible to thermal shock failure
• Outstanding hardness
• Extremely brittle
• Semiconductor
• Good thermal-neutron capture
3.Applications of boron cabide ceramics
• Abrasive grit or powder (grinding, lapping, polishing)
• Wear resistant engineering components (e.g. sand-blasting and water jet nozzles)
• Light weight ceramic armor
• Metal infiltration
• Boron source to produce other boron compounds
• High-temperature thermoelements
• Sintering additive for SiC advanced ceramics
• Neutron shielding material
