This book is a collection of diverse research activities on antimony where 12 groups of prominent authors from different part of the worlds presented their latest achievement on antimony-related materials. In the past, despite being widely known and utilized by many countries and cultures, antimony's status as an alchemical substance and its high toxicity have obscured understanding of the material, resulting in controversial usage of antimony, especially in medicine. Today, knowledge about antimony compounds has tremendously increased, and the application range of antimony has become much wider. Due to the diversity of the applications of antimony, researchers may stay focused on their own field while lacking familiarity with antimony-related activities in other fields.
