Applications for high temperature ceramics

The glass and metal processing and manufacturing industry, the chemical raw materials industry and industrial furnace construction use tubes made of densely sintered aluminium oxide ceramics for their plants. The operating conditions in these areas are extreme. The environment is extremely corrosive. Temperatures are above average. The shape accuracy of the ceramic must also be maintained at temperatures above 1,500 °C. The temperature in laboratory and industrial furnaces can be as high as 1,800 °C. The reason for the enormous heat resistance is the manufacturing process. During firing and sintering, fine-grained ceramic materials are compacted at temperatures at the melting point limit. This creates a stable structure. The homogeneity in the kiln guarantees a homogeneous result.

Further areas of application are thermal analysis, research and development, furnace construction, measurement and control technology and the steel industry. In dental technology, technologies are used to produce high-temperature ceramics to prevent discoloration of zirconia ceramics.

What other products are made of high-temperature ceramics?

Insulating rods, multiple capillaries, crucibles, annealing boxes, boats, grinding media, sliding blocks for furnace construction, plates, spare parts for piping systems and pre-wall technology and insulating beads round off the product range of this high-quality ceramic material. Electric-ceramic applications are ignition systems and heating elements. These include high-temperature heaters, connection and ignition cables, glow igniters and pellet igniters as well as ignition and ionization electrodes.

Properties of ceramic heating elements

In continuous operation, these technical ceramic components can withstand temperatures of up to 1,000 °C. Short-term temperatures between 1,300 °C and 1,500 °C are also possible. Depending on the geometry of the component, the heating times are in the range of seconds. They have both exterior and interior full insulation. High corrosion and oxidation resistance as well as high load capacity and controllability of the entire temperature range testify to outstanding quality. These properties make it possible to develop tailor-made solutions for the heating and electrical sectors. Customer-specific control of electrical data, electrical power and component dimensions can thus be realized.

Technical ceramics for high temperature applications

Gratings, charging stations, etc. are also made of ceramic fibre for applications in the high temperature range. Type 9020 industrial ceramics can be used up to 600 °C in the unfired state and up to 1,100 °C in the fired state. RAPOX and PYROLIT can even be used at temperatures of up to 1,600 °C. These ceramic materials convince both by thermal shock resistance and extremely good electrical insulation. The excellent price-performance ratio is another plus point.

bottom line

Heating conductor supports, injection moulding tools, heating rods and gas burner nozzles must withstand high temperatures. High-temperature ceramics are particularly suitable for these applications due to their heat resistance, dimensional stability, insulating properties and corrosion resistance. These properties are achieved by sintering and firing. A homogeneous firing process in the entire furnace area guarantees a uniform result. High-temperature ceramics offer heat resistance up to 600 °C even in the unfired state. In the fired state, the load capacity limit is approx. 1,800 °C for ceramic, industrial furnace linings. A distinction is made between permanent and one-off charges.

For uniquely high loads, maximum heat resistance of up to 1,600 °C is sufficient. Thermal shock resistance and insulating properties in the high temperature range are just as important. High temperature ceramic is designed for extremely extreme ambient conditions and convinces by excellent longevity. Customer-specific problem solutions represent a further challenge to the high-quality material. The price-performance ratio is a further criterion for the high acceptance of this technical material in the industrial sector.

This ceramic is ideal for all high temperature ranges.
