Armor plating made of fine-grain boron carbide and silicon carbide

An antiballistic armor-plating component, comprising a ceramic body made of a material comprising, as percentages by volume:

• between 35% and 55% of silicon carbide,
• between 20% and 50% of boron carbide,
• between 15% and 35% of a metallic silicon phase or of a metallic phase comprising silicon,
• and wherein, as percentages by volume of said material:
• the boron carbide grains with an equivalent diameter greater than 30 micrometers represent less than 5%,
• the boron carbide grains with an equivalent diameter less than 5 micrometers represent more than 15% and less than 35%,
• the silicon carbide grains with an equivalent diameter greater than 30 micrometers represent less than 5%, and
• the silicon carbide grains with an equivalent diameter greater than or equal to 5 micrometers and less than or equal to 30 micrometers represent between 35% and 55%.
