Molybdenum Trioxide (MoO₃) Nanopowder (99.9+%, 13–80 nm, Orthorhombic Crystal)

Description

Molybdenum Trioxide (MoO₃) Nanopowder / Nanoparticles (99.9+%, 13–80 nm, Orthorhombic Crystal)

Molybdenum Trioxide (MoO₃) Nanopowder is a high-purity orthorhombic crystal nanomaterial with particle sizes ranging from 13–80 nm and a purity level of ≥99.9+%. Produced through wet chemical purification and roasting methods, MoO₃ nanoparticles exhibit a very light blue color, talc-like texture, and excellent dispersibility.

With a specific surface area of 65 m²/g and a molecular weight of 143.94 g/mol, MoO₃ offers unique oxidation and catalytic properties. It melts at ~795°C into a brown liquid, is slightly soluble in water, and readily soluble in alkalis and acids. Upon reaction with phosphoric acid, it produces phosphomolybdic acid, making it valuable in catalysis and chemical synthesis.
