In a tunnel furnace, in which materials subjected to thermal treatment are contained in a holder arranged to pass continuously through the furnace, at least the parts of the furnace and holders, which came into contact with each other during this passage, are made of tungsten, and at least one of these parts contains 0À5 to 3% by weight of thorium oxide the remainder being of tungsten. A reduction in sticking between the parts is thus achieved. |
