HT Furnace / High temperature furnace
High temperature synthesis using a furnace in the context of Innovation-EL refers to the preparation of materials from a mixture of a number of oxides ground together to form a homogeneous powder. The mixture is then left to melt and react at appropriately high temperatures for a sufficient time within a crucible in air. Generally, this method may involve the use of controlled atmosphere (oxidizing or reducing) and is frequently used in the synthesis of glassy materials: after the starting materials have reacted, they are removed from the furnace and fast-cooled (or “quenched”) to form the glassy phase. Depending on the composition of the starting materials, crystalline phases may also form.
