Alumina coated evaporation sources
highly efficient small crucible style evaporation baskets


Introduction

    Alumina coated baskets evaporation sources

The alumina coated evaporation baskets are of novel design; combining the benefits of an evaporation basket with an alumina crucible. The result is a range of small alumina crucibles with highly efficient heating characteristics. The alumina coated basket forms an enclosure to hold the molten evaporation material. The power needed to heat this type of evaporation source is relatively low, making it compatible with lower power heating sources. The small size of the sources reduces the cost of evaporation materials. They are useful for thin film research, qualification experiments, physics, optical coating and manufacturing applications.

The alumina coated evaporation baskets offer the following field proven advantages:

  • upward evaporation with excellent upwards evaporation profile
  • easily mounted in standard evaporation source holders
  • high evaporation rates
  • long life time (alumina resists erosion by molten metals)
  • compatible with small to medium power supplies
  • usable for difficult to handle materials such as nickel and iron alloys
  • choice of six sizes to meet requirements


Recommended for evaporating materials
:

Nickel Tin  Copper Nichrome
Iron Antimony Cobalt  Permalloy
Gold  Bismuth Manganese  
Silver   Cadmium  Palladium  
Indium  Lead  Zinc  

There are six different types of alumina coated baskets; see the specifications table below. The power requirements  given are for a temperature of 1475°C. The maximum temperature of alumina coated baskets is not to exceed 1800°C. It is recommended to increase and decrease the power gradually to reduce the effects of thermal shock.
Most of the alumina coated evaporation sources are compatible with 100mm/4” source holders, which are fairly standard. It is not recommended to shorten the “legs” of the evaporation sources because the alumina coating is very brittle and can easily be damaged.
