Mechanically Activated Combustion Synthesis of B4C-TiB2 Nanocomposite Powder

Boron carbide is one of the hardest materials. The combustion method was used to synthesize B4C-TiB2 nanocomposite powder in a B2O3-Mg-TiO2-C system. An experimental study of the formation of B4C–TiB2 nanoparticles was conducted in the thermal explosion mode. A mixture of B2O3:TiO2:Mg:C at a molecular ratio of 3:1:12:1 was chosen to obtain the B4C–TiB2. This powder mixture was milled for differ...

intermetallic phase formation during combustion synthesis of mechanically activated ni-ti alloy

intermetallic phase formation and oxidation reaction during combustion synthesis (cs) of ni-ti equiatomic mixture are affected by mechanical activation (ma) and pre-heating conditions. important parameters are ignition time, reaction duration, temperature rise, microstructural change, titanium oxidation and intermetallic phase formation. superelasticity and shape memory effects are influenced b...

Mercury from Coal Combustion

A 1997 study in Minnesota indicated a relationship between mercury deposition trends and regional coal combustion (as well as other possible sources) spanning a period of two centuries (Engstrom and Swain 1997). Sediment core sampling from rural lakes in eastern Minnesota indicated a growth in mercury deposited from the air since the first half of the 1800s, with the amount peaking in the 1960s...
