Filament Coating

At SS Scientific, our Filament Coating services offer a choice between two premium options: Thoria or Yttria.

Coating Options

Filaments can undergo coating either as an integral part of our meticulous filament manufacturing process or as a specialised service for filaments supplied by our customers.  Notably, materials like Iridium often benefit from an emission coating to match the performance of tungsten.

Thoria and Yttria: Trusted Choices

The most common effective coatings are Thorium Oxide (Thoria), and Yttrium Oxide (Yttria), which has the advantage of being non-radioactive.

Thoria-Coated Filaments: Enhanced Performance

Thoria-coated iridium filaments boast an extended lifespan and reduced sensitivity to oxygen exposure.  These features contribute to superior performance and reliability over time.

Yttria-Coated Filaments: Environmental Advantages

Yttria emerges as a compelling alternative to Thoria, addressing environmental concerns associated with the latter.  Yttria-coated filaments not only require less power than their uncoated counterparts but also operate at lower temperatures to achieve equivalent emission levels.

At SS Scientific, our Filament Coating services ensure that your filaments benefit from cutting-edge materials and processes, providing longevity, efficiency, and environmentally conscious solutions.  Trust us for coatings that elevate the performance and reliability of your scientific instruments.
