Corinthian order simply an example of a votive column. A few examples of Corinthian columns in Greece during the next century are all used "inside" temples. A more famous example, and the first documented use of the Corinthian order on the exterior of a structure, is the circular Choragic Monument of Lysicrates in Athens, erected c. 334 BC. A Corinthian capital carefully buried in antiquity in the foundations of the circular "tholos" at Epidaurus was recovered during modern archaeological campaigns. Its enigmatic presence and preservation have been explained as a sculptor's model for stonemasons to follow in erecting the temple dedicated to
Ionic compound for high-temperature solid-state synthesis. Many metals are geologically most abundant as ionic compounds within ores. To obtain the elemental materials, these ores are processed by smelting or electrolysis, in which redox reactions occur (often with a reducing agent such as carbon) such that the metal ions gain electrons to become neutral atoms. According to the nomenclature recommended by IUPAC, ionic compounds are named according to their composition, not their structure. In the most simple case of a binary ionic compound with no possible ambiguity about the charges and thus the stoichiometry, the common name is written using two words. The
