General Description

Terbium boride is a chemical compound composed of terbium and boron, with a chemical formula of TbB2. It is a rare earth metal boride with a metallic luster and high thermal and electrical conductivity. Terbium boride is a refractory material, meaning it has a high melting point and is resistant to heat and wear. It is also known for its superconducting properties at low temperatures. Terbium boride is used in various applications, including in the production of superconducting materials, as a component in high-temperature thermoelectric devices, and in nuclear reactor control rods. Additionally, it has potential uses in electronic and magnetic devices due to its unique magnetic and electrical properties.

Mg-assisted autoclave synthesis of RB6 (R = Sm, Eu, Gd, and Tb) submicron cubes and SmB6 submicron rods

Submicron crystalline rare-earth hexaborides (RB6; R = Sm, Eu, Gd, and Tb) have been successfully prepared by a facile one-step solid-state reaction of RCl3·OH2O, B2O3, and Mg powder in an autoclave at the relatively low temperature of 500°C. By controlling the reaction, conditions, submicronsized cubes (RB6) and rod- and needlelike SmB6 are obtained. The possible growth mechanism of the 1D SmB6 structures has also been discussed. The XRD patterns of the products show that all of the hexaborides can be indexed to a cubic phase with high crystallinity and high purity. The field-emission scanning electron microscopy (FESEM) and TEM images display their cube-, rod-, and needlelike morphologies. The selected-area electron diffraction (SAED) patterns reveal the single-crystalline nature of the products.

Thermodynamic functions for heavy rare-earth hexaborides as measured by calorimetry in the temperature range from 5 to 300 K

The molar heat capacities of gadolinium, terbium, and dysprosium hexaborides were measured over the temperature range 5-300 K. The temperature dependences and the standard values of the enthalpy, entropy, and the Gibbs energy were calculated by taking into account the nuclear contribution to the heat capacity.
