# The Dual-Use and Related Goods (Export Control) Regulations 1995, Paragraph 163: DEFINITIONS OF TERMS IN THIS ANNEX


“Superconductive” (1 3 6 8) means materials, i.e., metals, alloys or compounds, which can lose all electrical resistance, i.e., which can attain infinite electrical conductivity and carry very large electrical currents without Joule heating.
N.B.: The “superconductive” state of a material is individually characterised by a “critical temperature”, a critical magnetic field, which is a function of temperature, and a critical current density which is, however, a function of both magnetic field and temperature.
