Abstract

Borides are important compounds in the materials chemistry world due to their interesting properties. Many boride compounds like LaB6 are well-known for their high electron emissivity, while other compounds like MgB2 exhibit superconductivity. Recently it has been suggested that binary borides like osmium boride or rhenium boride might be among the hardest materials known. As the dimensions of any solid are reduced to the nano scale, the surface to volume ratio is highly enhanced. The increased surface area in the nano-structured geometry makes them especially useful in devices where the functional surface area of the solid plays a critical role. The boride nano-structures are expected to show greatly enhanced properties and hence, the generation of boride nano-structures using simple and innovative routes is the current interest of this research. Some preliminary results obtained from synthesis routes involving solution-mediated hot-injection technique for the systems, LaB6, MgB2 and nickel boride would be presented.
