What is ISO 10143 - Determination of the electrical resistivity of granules about?
ISO 10143 is applicable to carbonaceous materials for the production of aluminium.
ISO 10143 specifies a method for the determination of the electrical resistivity of granular carbon (calcined or graphitized) used in the manufacture of carbon electrodes for the production of aluminium.
The measurement of electrical resistivity assists in assessing the extent of coke calcination. The electrical resistivity of the coke aggregate will influence the electrical resistivity of the coke electrodes made from it.
In general, a more highly calcined coke will have a lower electrical resistivity if other factors, such as grain size, are similar.
Who is ISO 10143 - Determination of the electrical resistivity of granules for?
ISO 10143 on the determination of the electrical resistivity of granules is useful for:
- Manufactures of carbon electrodes
- Companies producing aluminium
- Steel industries
Why should you use ISO 10143 - Determination of the electrical resistivity of granule?
Calcined coke is an essential part of the aluminium industry. It is used to produce granular carbon for aluminium production.
ISO 10143 provides you with the principles, apparatus, sampling and procedure. That will help you to determine, measure and assess the electrical resistivity of granules.
