“…The majority of these compounds are the structural derivatives of elemental α-rhombohedral boron (α-B12) with general stoichiometry: B12Xy (where X is interstitial atom, y ≤ 2). They received a considerable attention due to the high hardness, chemical inertness, thermal conductivity, radiation resistance and unusual electronic properties [2][3][4][5]. For instance, boron carbide B12C3 is hard compound widely used as abrasive and armor material [6,7], boron suboxide B12O2 is the hardest known oxide [8,9], and B12As2 was found to be extremely stable under electron bombardment and able to the self-healing [10].…”

Two novel of boron-rich selenides, orthorhombic B6Se and rhombohedral B12Se, have been recently synthesized at high pressurehigh temperature conditions. Room-temperature compressibilities of these phases were studied in a diamond anvil cell using synchrotron powder X-ray diffraction. A fit of experimental p-V data by third-order Birch-Murnaghan equation of state yielded the bulk moduli of 155(2) GPa for B12Se and 144(3) GPa for B6Se. No pressure-induced phase transitions have been observed in the studied pressure range, i.e. up to 35 GPa.

Thermal expansion of α-rhombohedral boron (α-B12) and two isostructural boron-rich pnictides (B12P2 and B12As2) has been studied between 298 and 1280 K by high-temperature synchrotron X-ray diffraction. For all studied phases no temperature-induced phase transitions have been observed. The observed temperature dependencies of the lattice parameters and unit cell volumes were found to be quasi-linear. Variation of the thermal expansion coefficients in the group of boron-rich pnictides (B13N2 -B12P2 -B12As2) was analyzed.

“…The application of these materials is also can be used in many fields including catalysis, sensor, and photocatalysis (Marschall and Wang, 2014). One of the interesting element is boron due to metalloid properties and Lewis acidity of this element and compounds (Slack and Morgan, 2015). Boric acid is solid compound and has been applied as catalyst or support catalyst.…”

Synthesis of the borate-based compound with ZrOCl 2 to form B 2 O 3 -ZrO 2 has been conducted. The compound was characterized by FT-IR spectrophotometer, X-ray diffraction, acidity and thermal stability test. The results showed that the FT-IR main vibration spectrum of B 2 O 3 -ZrO 2 compound has appeared at wave number 401.2 cm -1 for Zr-O bonding vibration, 617.2 cm -1 for B-O-B bonding vibration and 910.4 cm -1 for B-O bonding vibration. The XRD diffraction pattern shows B 2 O 3 -ZrO 2 compound has an amorphous structure. The FT-IR spectrum after saturated with ammonia and potentiometric titration indicates that the compound of B 2 O 3 -ZrO 2 has acidic properties with a strong level of acidity. Thermal stability test shows that the B 2 O 3 -ZrO 2 compounds have high stability on temperature with increasing crystallinity after the compound was heated at 700 °C.
