Alumina Tubes for High Temperature Ceramic tubes were first used in ancient Egypt around 3000 BC. They were made by pouring molten clay into a mould and allowed air to escape through holes on the bottom. The clay would cool and harden inside the mould, creating a hollow cylinder. The first recorded use of alumina ceramics dates back to the year 535 BC when Chinese alchemists discovered how to prod...
