Graphite electrode, counter-spherical tip, 6.15mm dia, 38.10 mm long, 99.9995% (metals basis), Thermo Scientific Chemicals

Description

• The surface modification of graphite felt with concentrated sulfuric acid has led to dramatic improvement in the electroactivity of this material in the vanadium redox cell
• A cell resistance of 2.50cm 2 and energy efficiency of 91% were obtained in the vanadium cell, after the graphite felt electrode material was treated with boiling concentrated sulfuric acid for 5 hour
• Graphite felt treated thermally at 400°C exhibited the greatest improvement in performance of the vanadium cell
• Graphite electrode are used in primarily in electric furnace steel manufacturing
• It can provide high level of electric conductivity and capability of sustaining the extremely high level of generating heat
• It is also used in the refinement of steel and similar smelting process
• This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio
• Some documentation and label information may refer to the legacy brand
• The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
