MSE PRO Conductive Titanium Suboxide Nanowires, 100nm x 5 um, 1g

Introduction

MSE PRO Conductive Titanium Suboxide Nanowires (TiOₓ-NW), commonly referred to as titanium black or Magnéli-phase titanium oxide (Ti₄O₇), are low-valence titanium oxides featuring a unique partially reduced Ti⁴⁺/Ti³⁺ mixed-valence structure.

Unlike conventional TiO₂, these materials exhibit metal-like electrical conductivity (≈ 1000 S/cm, significantly higher than carbon black at ≈ 100 S/cm) along with exceptional chemical and electrochemical stability, making them highly valuable for a wide range of advanced applications.
