Nanoparticle research has progressed by leaps and bounds mainly due to the unexpected properties exhibited by elements by altering their atomic and molecular properties. Nanoparticles dominate many of the applications in fields like biomedicine, electronics, pharmaceuticals and cosmetics. This article will elaborate on the properties and applications of titanium boride nanoparticles.
Titanium boride (TiB2) nanoparticles are black spherical particles having a high surface area. They are available in coated, dispersed, high and ultra high purity forms. These particles exhibit very good ceramic properties.
Some of the key properties of these nanoparticles are high hardness, high temperature chemical stability, high melting point, acid-resistance, wear resistance and thermal shock resistance.
Titanium belongs to Block D, Period 4 while boron belongs to Block P, Period 2 of the periodic table. It is important that these particles are stored under vacuum and dry conditions and should not be subjected to stress.
