When carbon impurities trigger the synthesis of alpha boron at high pressure and high temperature
Amrita Chakraborti, Yeonsoo Cho, Jelena Sjakste +5
The role of carbon in the formation of alpha boron at high pressure and high temperature (HPHT) has been investigated by combining HPHT experiments and density functional theory (D…

Synthesis of boron carbide from its elements up to 13 GPa
Amrita Chakraborti, Nicolas Guignot, Nathalie Vast +1
The formation of boron carbide under high pressures and from elemental reactants has been studied and optimum parameters have been determined by varying the (P, T, reactants) condi…
