Titanium carbide – Titanium boride composites by self propagating high temperature synthesis approach: Influence of zirconia additives on the mechanical properties

Combustion Synthesis of NbB2–Spinel MgAl2O4 Composites from MgO-Added Thermite-Based Reactants with Excess Boron

“…In this arrangement, the hexagonal nets of metal atoms and triangle nets of pure boron atoms are alternately stacked along the c axis [1]. Besides their melting points exceeding 3000 • C, they possess a unique combination of high hardness, thermal conductivity, electrical conductivity, excellent chemical stability, corrosion resistance, and thermal shock resistance [2][3][4][5]. They have found a broad range of applications in the mechanical, automobile, aerospace industries, etc.…”

“…MgAl 2 O 4 is of particular interest due to its exceptional mechanical, thermal, and optical properties, such as high melting point (2135 • C), high hardness (16 GPa), relatively low density (3.58 g/cm 3 ), high mechanical strength (135-216 MPa), good transmittance in the wavelength range of 0.25 to 5.0 µm, high thermal shock resistance, high chemical inertness, low dielectric constant, and low thermal expansion coefficient [12,13]. MgAl 2 O 4 spinel has a close-packed face-centered cubic (fcc) structure of space group Fd3m (number 227).…”

Low-Temperature Synthesis of Monolithic Titanium Carbide/Carbon Composite Aerogel

“…[ 1 , 2 , 3 , 4 , 5 ]. Traditional synthesis methods of carbide include the direct carbonization method [ 6 , 7 , 8 ], the carbothermic method [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ], self-propagation high-temperature synthesis [ 16 , 17 , 18 , 19 , 20 ], the mechanical alloying method [ 21 , 22 , 23 , 24 ], the microwave method [ 25 , 26 ], the molten salt method [ 27 , 28 , 29 , 30 ] and the plasma method [ 31 , 32 ]. The carbothermic method is widely promoted because it possesses the advantages of low cost, simple equipment, high production efficiency and mass production capacity.…”
