Descrição geral

Anhydride can be obtained by heating boric acid at temperatures higher than 160oC.1

Aplicação

Reducing boron anhydride in the presence of sodium yields amorphous boron. Whereas reducing in the presence of aluminum at high temperatures affords crystalline boron. 1

Using a two-dimensional multiple-quantum (MQ) double rotation (DOR) experiment the contributions of the chemical shift and quadrupolar interaction to isotropic resonance shifts can be completely separated. Spectra were acquired using a three-pulse triple-quantum z-filtered pulse sequence and subsequently sheared along

Al-rich single-crystal mullite [Al(2)(Al(2.8)Si(1.2))O(9.6)] nanowires were prepared by B(2)O(3)-doped molten salts synthesis. The nanowires have diameters in the range 30-50 nm and typical lengths of 1 microm. The mullite nanowires were well dispersed and facile to obtain.
