We are pleased to offer high quality Graphene materials for your research needs. As distributors for leading international Graphene producers Advanced Graphene Products we are ideally placed to support your project.

High Strength Metallurgical Graphene® is a large-area polycrystalline graphene sheet, manufactured with a metallurgical method based on graphene liquid phase growth. HSMG® is crystallized on a liquid metal surface which allows each graphene particle to rotate and rearrange until fitting perfectly into the crystallizing graphene sheet.

Advantages

  • Much stronger and more durable than CVD graphene
  • Can be produced in large quantities
  • Much shorter production time
  • Available in large variety of sizes from 10 x 10mm up to 200 x 90mm
  • Semiconductive qualities

Designed by researchers from Lodz University’s department of Materials Science and Engineering which , alongside APG, has been developed into a highly efficient production process.

Production Method

A unique method of growing graphene on a liquid metal matrix;

Based on formation of graphene on liquid metal allowing each graphene particle to rotate and rearrange until fitting perfectly into the crystallizing graphene sheet.

Additionally, this method provides a zone cleaning effect (e.g. pushing the contaminations outside of graphene flakes) which eliminates impurities.

Properties

  • Grown on liquid metal matrix
  • Monocrystalline flakes up to 1 mm
  • In tensile tests elongation 100 %
  • Single and multilayer sheets of any size
  • Very high coverage and continuity (min 95 %)
  • Easily transferable onto various substrates
  • Stability without a substrate
  • Stable negative thermal coefficient of electroconductivity
  • Stable mechanical and physical properties under thermal fatigue conditions
