Boron carbide ceramic plates are produced through advanced powder processing and sintering techniques:
- Powder Production: Boron carbide powder is synthesized via carbothermal or magnesiothermal reduction of boron oxide with carbon.
- Powder Processing: Milling and classification ensure uniform particle size and purity.
- Sintering: Hot pressing or spark plasma sintering densifies the powder into solid ceramic plates with minimal porosity.
- Machining: Diamond tools are used to cut and finish the plates to precise dimensions.
- Composite Assembly: Plates are often backed with composite fibers like Kevlar or Dyneema for enhanced impact absorption.
Boron carbide's hardness makes it highly resistant to abrasion and penetration. This allows the plates to withstand impacts from armor-piercing rounds and shrapnel, making them ideal for personal and vehicle armor.
