Scalable and Facile Synthesis of Small (Less than 10 nm) High Purity Titanium Diboride Nanoparticles

Tech ID: 29914 / UC Case 2018-323-0

Summary

Researchers at the UCLA Department of Mechanical and Aerospace Engineering have developed methods to synthesize titanium boride nanomaterial through a scalable and facile synthesis scheme.

Background

Metal borides offer metallic, semiconducting, or magnetic properties depending on the metal and their composition. When nano-scale metal borides are dispersed throughout a metallic matrix, they behave as nano-scale reinforcements in the metallic matrix. The resulting metal matrix nanocomposites (MMNCs) can be used in diverse applications, including impact-resistant armor, cutting tools, crucibles, neutron absorbers, and wear-resistant coatings. Nano-scale metal borides can also be used in polymer composites to produce polymer metal nanocomposites (PMNCs) for applications such as conducting polymers for temperature or current sensing, and electromagnetic shielding for electronic boards. Titanium diboride (TiB2) is a particularly interesting metal boride for use in MMNCs and PMNCs because of its unique physical and chemical properties. However, commercially available titanium boride nanoparticles typically have a large size (~58 nm) and poor purity. Methods for producing high purity and small size TiB2 nanoparticles are highly desirable for the aforementioned applications.

Innovation

Researchers at UCLA have developed methods to produce titanium diboride nanoparticles through a scalable and facile synthesis. This methodcan produce titanium diboride nanoparticles smaller than 10 nm, with high purity.

Applications

TiB2 nanoparticles can be used as reinforcement/filler phase in a broad range of material systems (i.e. metals, ceramics, and polymers) to offer significant increase in mechanical, thermal, chemical and electrical properties

Advantages

  • Higher purity
  • Smaller nanoparticle size (average size 8.1±0.4 nanometer)
  • Cheaper production cost (estimated to be 1/10 of conventional methods)
  • High electro-conductivity
