High-Temperature Synthesis Department
A novel synthesis method for AlB₁₂ has been developed and implemented, forming the basis for a semi-industrial technology to obtain submicron (100–150 nm), technically pure, single-phase aluminum dodecaboride powders.
Synthesis procedures have been elaborated, and the properties of the following composite systems have been studied:
synthesized across a wide range of concentrations; 100 % technological yield, no cracking defects, load resistance up to 500 N (Vickers test), high thermal conductivity and electromagnetic permeability
capability to form nano- and microsized particles, use of a liquid phase as a compaction activator, high hardness and fracture toughness
complete component interaction, exceptional mechanical strength, and fracture toughness up to 7–8 MPa•m¹ᐟ²
From these ceramics, laminated armor elements have been fabricated and have shown positive results in ballistic testing.
In addition, synthesis procedures have been developed and the properties of six boron-carbide-based ceramics (B₄C) have been investigated.
The introduction of specific additives enabled a reduction in hot-pressing temperature by 200–300 °C.
Hv = 24.1 GPa (at 49 N load)
K₁c = 3.67 ± 1.2 MPa·m¹ᐟ²
Rᵦm = 285 MPa
R𝑐s = 378 MPa
P ≈ 0 at a specific density of γ = 2.5–3.0 g/cm³
💡 The developments of the High-Temperature Synthesis Department form the scientific and technological foundation for advanced heat-resistant, armor, and anti-radiation materials with promising applications in defense, aerospace, and high-performance industrial systems.
