| Summary |
A material that enchants us as ruby or sapphire and is applied in watches or lasers. A material that gives us a better life in the form of implants. A material that provides irreplaceable technical services with its hardness and heat resistance. A fascinating material. Its name is aluminium oxide. In this book you will find a lot of exciting and often astonishing information about this extraordinary material. First, the necessary facts about the substance aluminium oxide are given. Then the world of the gemstones ruby and sapphire is described. And finally, the world of Aluminium oxide as well as technical ceramics is illuminated. The author Dr. Bozena Arnold (formerly Boczek) is professor emerita of materials engineering at HAW Hamburg University of Applied Sciences and has many years of experience in imparting materials engineering knowledge. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation |
