Intro. Schematic Illustration of Boron Carbide (B4C) Sintering Methods and Additives
Center Panel: A large B4C powder particle (grey) is shown fracturing under pressure. Arrows indicate the application of pressure or heat during different sintering methods.
Left Side: Five sections represent different sintering methods:
Pressureless Sintering (PLS): B4C powder particles are loosely packed together. Minimal densification is shown with small arrows indicating limited particle bonding.
Hot Pressing (HP): B4C powder is under pressure (represented by downward arrows) while heated (indicated by flames). Particles show increased bonding and some densification.
Hot Isostatic Pressing (HIP): B4C powder is enclosed in a container and subjected to high pressure (arrows coming from all directions) and heat (flames). Particles are more densely packed with significant bonding.
Microwave Sintering: B4C powder is exposed to microwave radiation (wavy lines). Particles show some initial bonding and densificat
