Oxide Powder

Bismuth (III) oxide is the most industrially indispensable compound of bismuth. Bismuth trioxide powder is commonly utilized to produce the "Dragon’s eggs” effect in fireworks. Bi₂O₃ as it is principally an ionic conductor and in addition to electrical properties, thermal expansion properties are very important when considering possible applications for solid electrolytes.

Bismuth (III) oxide has also been utilized as a sintering additive in the Sc₂O₃- doped zirconia system for intermediate temperature SOFC. Bismuth oxide acquired great attention since they are used in the wide area of applications such as in glass technology. The fabricated glasses are characterized by a high dielectric constant, high density, high refractive index, and extended transmission in mid-IR, etc.

Bismuth trioxide powder is an oxidic semiconducting material and it shows different physical and chemical properties determined by its numerous modifications. In the form of thin films, it possesses significant values of the bandgap, refractive index, and dielectric permittivity. Besides, it shows remarkable (UV) photosensitivity and photoluminescence. Bismuth oxide recommends it for a wide range of applications in the solid-state technology: from optical coatings to optoelectronics and ceramic glass manufacturing. A series of technological applications of bismuth oxide thin films use its photocatalytic properties and the caption of polar gases in the gas sensors.

Bismuth oxide glasses have an extensive range of applications in distinct fields such as layers for optical, glass ceramics, electronic devices, thermal and mechanical sensors and reflecting windows. The glasses of bismuth are very suitable for utilizing, for instance, lead-free low-softening point dielectric glasses for thick film conductors, plasma display panel, and sealing glasses for metals, etc. Moreover, bismuth glasses could also be utilized as a lead-free high-density radiation shielding window (RSW) glasses.
