Bismuth Oxide (Bi2O3) Micron Powder, Purity: 99.5+%, Size: 1-5 µm

Description

Bismuth Oxide (Bi₂O₃) Micron Powder – 99.5+% Purity, 1–5 µm Size

High-Purity Bismuth Oxide Powder for Semiconductor and Electronic Applications

Product Overview

Bismuth Oxide (Bi₂O₃) Micron Powder, with a particle size of 1–5 µm and 99.5+% purity, is a high-performance material widely used in the fields of semiconductors, electronic ceramics, and photonic devices. This fine white to yellowish powder offers unique electrical and optical properties, particularly high refractive index, wide bandgap, and excellent ionic conductivity.

Its low toxicity and environmental friendliness make Bi₂O₃ a safer alternative to traditional heavy metal oxides in modern device manufacturing. Additionally, its strong thermal stability and oxide ion conductivity support high-temperature applications such as solid oxide fuel cells (SOFCs), varistors, and sensors.
