Historical Armour made of leather, particularly that used by the Romans.

Passing by the Corium Bubulum of the Classical Ancients, we see in an old charter, dated 1036, "Stallus Sutoris Vaccæ," i. e. the stall of a shoe-maker who used cow-skin.1825, Thomas Dudley Fosbroke, Encyclopaedia of antiquities, and elements of archaeology, classical and mediæval:

noun

Etymology From core + -ium. Apparently coined in 1974 by Martin Peehs, a German nuclear engineer.

A lavalike mixture of fissile material created in a nuclear reactor's core during a nuclear meltdown.

Nuclear physics

Mexico was given $100,000 to do a series of experiments in which small amounts (10 to 20 grams) of stainless steel and corium (a mixture of 55 percent iron, 10 percent zirconium, and 35 percent uranium dioxide) will be melted and then flooded with water in an arc-melting chamber.1975 21 October, Hearings on the Nuclear Initiative: Technological Concerns in Nuclear Reactor Safety, Sacramento (CA): California Legislature Assembly Committee on Resources, Land Use, and Energy:
Previous studies of the thermal behavior of corium in a degraded nuclear reactor have focussed primarily on the process of heat transfer within the corium.1991, Sheau-Wen Shiah, Fan-bill B.

The materials of the nuclear reactor—nuclear oxide fuel and fission products, cladding, metallic alloys, moderator, absorbers, structural materials, coolants, concrete, and so on, could melt to form complex, multiphases, and aggressive mixtures known by the general term corium.2011, Pascal Piluso, “Appendix 1: Corium Thermodynamics and Thermophysics, 2.
