A second option for thermal evaporation is to use a shielded tantalum crucible heater with a tall, intermetallic crucible. Thin films of titanium can be evaporated from intermetallic crucibles. However, film thickness may be limited to 500 angstroms, and the crucible may need to be replaced for each subsequent run. Intermetallic crucibles are composed of titanium boride (TiB2) and boron ...
Heat Shielded Crucible Heaters. Shielded crucible heaters provide uniform heating to the installed crucible and allow very high rates as well as high temperatures, up to 1800°C, to be achieved.

The shielded and double shielded crucible heaters are uniquely designed to increase thermal efficiency and allow you to reach higher, more uniform temperatures up to 1800°C. Heater life is increased, crucible fracture is reduced and your vacuum system is protected from excessive heat radiation. These offer high re-usability, superior thermal shielding and rigid construction. Custom crucible ...

It is possible to use a shielded, tantalum crucible heater with an aluminum oxide crucible. However, this method may be unsuccessful because tantalum baffle boxes cannot withstand high temperatures. In order for silicon dioxide to sublime and evaporate, the temperature of the baffle box must be between 1,500°C and 1,800°C. Once the material's temperature is within this range, there is ...
