Silicon Carbide Heating Elements
STARBAR-Heating Elements are produced from recrystallised silicon carbide. The high density of 2,4 g/cm3 assures a maximum of durability and a high strength. The nominal element-resistance is measured at a temperatur of 1071 °C. The possible element-power depends upon the furnace-temperature and furnace-atmosphere. The aluminium metallized cold-ends assure a proper electrical contact for the current entry.
Areas of application
Typ: DB
Element with enlarged thickened cold-ends. The element consists of a high-resistance hotzone and two sintered cold-ends, which have, because of its bigger cross-section, a essential lower resistance-value as the hotzone.
Typ: SE
Is build out of a tube with a spiral cutted in. This spiraled area represents the hotzone of the element, which has instead of the cold ends a very high resistance. Elements with separated hotzones are possible.
Typ: RR
Element with a constant diameter along the whole length. The element is build of a hotzone in the middle and two cold ends, which are metallized with aluminium, to reduce the resistance and the temperature in the cold-ends.
Typ: SER
Because of the bifilar spiral-builded hotzone the both cold-ends are located at one side of the element. So this form of element is specially suitable for furnaces which are difficult to access. SER-elements will be delivered with flexible terminal-clamps.
Typ: U and W
Is build out of two parallel fixed heating elements which are connected through a low resistance bridge circuit of SIC. Each heating element is partitioned into a hotzone and a zone of cold ends. The U-element is used for a 1-phase-element …
… and the W-element for a 3-phase-element.
Typ: TSR
Is a thinwalled model of the bifilar spiral-element for the application of a muffle type furnace. Because the annealing-good is fully surrounded from the heating element, it is specially suitable for the application of thermical analyses, calibration of thermocouple, etc. The two electrical terminals are located at one side.
mountings and mating components
- screwed terminal clamps
- mounting parts for terminal-straps, form M and W
(M = for manual mounting, W = for mounting with tools - terminals made of flexible aluminium-strand
Typ A: from heating element to voltage supply source
Typ B: for serial connection
Typ C: for strap-extension

230 Volt Hot Surface Igniters
Article number: 910000100
Starlite hot surface igniters from the American manufacturer I-Squared-R are made of high purity, self-binding silicon carbide. The hot zone area is specially formed and has maximum strength to achieve a long service life. Starlite hot surface igniters operate in a voltage range of between 208 and 230 Volt and are used as micro heaters in laboratory furnaces, as high temperature igniters to burn off inert gas or in batch furnaces, for example. In the United States and Great Britain in particular, Starlite hot surface igniters are used to ignite gas in gas boilers and in domestic applications, such as gas-fired dryers and water heaters. Many other applications are also possible.
Features and Benefits
Starlite hot surface igniters are the most robust silicon carbide igniters (SiC igniters) available on the market and can be customised to your applications’ electrical and thermal specifications. Starlite ignition electrodes are partially shock-resistant, are supplied with optional individual connector sockets and can be ordered with a non-standard connector cable length (approx. 125 mm). For robust use is SIC-igniter have established with metallic housing (Protection Cage).

Physical Properties
- Time available to reach 982 °C (at 207 Volt) = 20, 30 or 50 sec. depending on the specification
- Current range at 230 Volt = 1.8 – 4.5 Amp (customer-specific limits are available as an option within this range)
- Temperature range at 230 Volt = 1.204 – 1.537 °C (igniter: customer-defined limits are available as an option within this range)
- Plug material = normal temperature-resistant industrial materials are used. The standard 230 Vigniter (article no. 910000100) is supplied without a plug
- Connection ends = industrial-standard materials are used, optionally also according to customer requirements
- Connecting cables = standard cables are resistant to 200 °C (or cables in lengths and grades defined by the customer, if specified)
- Authority approval = CSA approval
