Thermal conductivity behavior of boron carbides [PDF]
Physical Review B, 1985 Knowledge of the thermal conductivity of boron carbide is necessary to evaluate its potential for high temperature thermoelectric energy conversion applications. We have measured the thermal diffusivity of hot-pressed boron carbide B1-xCx samples as a function of composition (0.1 ≤ x ≤ 0.2), temperature (300 K to 1700 K) and temperature cycling.

Study of the ability of self-assembled N-vinylcarbazole monolayers to protect copper against corrosion [PDF]
Journal of the Serbian Chemical Society, 2002 The effect of boron, in the amounts of 0.26, 0.39, and 0.59 wt.%, on the volume fraction and structure of carbides in Cr white irons was examined. It was demonstrated that the addition of boron can change the microstructural characteristics of white iron
