The invention involves a heat-insulating insulation element for high-temperature applications and a method for manufacturing the same. The object of the invention is to indicate options for effective heat insulation, which can also be used for high-temperature applications at temperatures above 100 °C, preferably above 500 °C, while reducing the required space, as well as the temperature at the outer surface, with respect to conventional solutions. A heat-insulating insulation element for high-temperature applications as per the invention features an outer gas-tight envelope. Pressure is maintained below atmospheric pressure within the envelope, which is made of a ceramic material. In addition, the envelope is sealed in a gas-tight manner via an integral joint by means of a temperature-stable filler material at a joint area or opening. However, sealing can also be achieved only or in addition by a form-fit connection. Various ceramic materials can be used for the envelope. |
