摘要： An electrical resistance element consists mainly of a silicide phase according to the formula Mo(Si 1-x Al x ) 2 , which phase forms alumina on the surface of the element. The element is intended to be used in connection with sintering of metal powder. Because of its surprisingly good ability to form an alumina layer on the surface, this material has shown to be very resistant against corrosion at high termperatures over 1500 °C in both reducing and oxidizing atmosphere.

摘要： The invention relates to the production of materials intended to be used in an oxidizing medium at high temperatures in order to manufacture high temperature electrical heaters, parts, transducers and instruments working at the temperatures equal to or higher than 1900 °C. The inventive heat resistant material is based on silicide-solid solution (Mo,W)5Si3 and (Mo,W)Si2 and on Novotny phase (Mo,W)5Si3C which also comprises molybdenum and wolfram. Said material can be used for manufacturing parts made completely thereof and also for producing protective coatings and soldered joints for a large range of other heat resistant materials like 'REFSIC' composites, carbon materials, silicon-carbide materials, refractory metals and alloys thereof. Multiple possibilities for changing properties by controlling phase composition, and a large variety of structural peculiarities of unilayer and multilayer protective coatings makes it possible to manage heat resistance and rapid temperature-change resistance, combined thermal deformation of the coating itself and parts manufactured with the aid of soldering other heat resistant materials with the use of the inventive material. The inventive electric heaters can comprise working parts and current leads made of said material, provided with soldered joints and protective coatings also made of the inventive material in various combinations of materials and constructions.
