High-pressure Syntheses and Characterization of the Rare Earth Borates RE5(BO3)2F9 (RE=Dy, Ho)
The new rare earth fluoride borates RE5(BO3)2F9 (RE = Ho, Dy) were synthesized under highpressure/high-temperature conditions of 1.5 GPa, 1250 ◦C for Dy5(BO3)2F9 and 2.5 GPa, 1200 ◦C for Ho5(BO3)2F9 in a Walker-type multianvil apparatus from the corresponding rare earth oxides, rare earth fluorides, and boron oxide. The single-crystal structure determinations have revealed that both compounds a...
متن کاملRE4B4O11F2 (RE = Pr, Nd): Two New Rare-earth Fluoride Borates Isotypic to Gd4B4O11F2
Dedicated to Professor Heinrich Nöth on the occasion of his 85th birthday The rare-earth fluoride borates RE4B4O11F2 (RE = Pr, Nd) were obtained in a Walkertype multianvil device from the corresponding rare-earth oxides and fluorides, and boron oxide. Pr4B4O11F2 was obtained under high-pressure/high-temperature conditions of 8.5 GPa/1150 ◦C, and Nd4B4O11F2 at 8 GPa and 1300 ◦C. The single-cryst...
متن کاملBoric Acid and Borates
Boric acid and its chemical relatives are pesticides that are derived from the element boron. Boron rarely occurs alone and is typically found in combination with other elements; common combinations are boric acid or borates.1 Unlike many pesticides which are synthetic compounds,2 boric acid and related pesticides are naturally occurring compounds.1 Boron compounds are widely found in rivers, s...
