Lanthanum Oxide Nanoparticles La2O3 Nanopowder

Product Overview

Description

Introduction

This article discusses about the properties and applications of lanthanum oxide nanoparticles. Lanthanum is a Block F, Period 6 element, while oxygen is a Block P, Period 2 element. Lanthanum oxide is an odorless, white solid. It is insoluble in water, and soluble in dilute acid. Lanthanum oxide nanoparticles have high photoelectric conversion efficiency.

The morphology of lanthanum oxide nanoparticles is spherical, and they appear as a white powder. They are strongly hygroscopic. Lanthanum oxide nanoparticles are graded as irritant, and can cause irritation to skin, eyes, and related breathing difficulties.
