Tellurium, element 52, is a metalloid used at low concentrations in the formulation of various steel, rubber, and ceramic products, among others. Tellurium toxicity is rare ( Larner 1995 ), but it is of interest as a model system for study of the type of metabolic insult that can lead to specific demyelination.Web

Vulcanization is a chemical process in which elastomeric materials are heated with an agent (generally sulfur), an activator, an accelerator, and sometimes a retarder to form a cross-linked molecular network. This results in improved properties such as elasticity, resilience, tensile strength, viscosity, hardness, and weather resistance [3].Web
