The HTK range of Carbolite Gero high temperature furnaces consists of metallic furnaces made of Molybdenum and Tungsten.
The rectangular design with a front door allows for easy loading and unloading. The HTK range is available in three different sizes. The smallest designs with a capacity of 8 litres and 25 litres are typically employed by laboratories for research and development. The 80 litre furnaces are predominantly used as pilot manufacturing systems or large scale production.
The metallic furnaces constructed of tungsten (HTK W) or molybdenum (HTK MO) permit the greatest possible purity of inert atmosphere and final vacuum level in the high vacuum region (5 x 10-6 mbar). Upon request, an ultra-high vacuum can be configured. Common gases that are typically used include: Nitrogen, Argon, Hydrogen or mixtures.
The heating elements are made from the same metallic material as the insulation. The heating insulation is constructed of several radiation shields constructed from tungsten or molybdenum with respect to the furnace type selected. A retort can be utilized for gas flow guidance or to improve the temperature uniformity. The maximum temperature for the HTK W is 2200 °C and 1600 °C in the HTK MO.
