Eigencolloid

Eigencolloid is a term derived from the German language (eigen: own) and used to designate colloids made of pure phases. Most often such colloids are formed by the hydrolysis of heavy metals cations or radionuclides, such as, e.g., Tc(OH)₄, Th(OH)₄, U(OH)₄, Pu(OH)₄, or Am(OH)₃. Colloids have been suspected for the long-range transport of plutonium on the Nevada Test Site.
