Effect of electrical resistance on ramp rate in cold end portion of SiC heating elements

Controlling the electrical resistivity of porous silicon carbide ceramics and their applications: A review

“…Commercial SiC heating elements are manufactured via the recrystallization of SiC particles and constitute a porous structure, which has a theoretical density of approximately 2.9-3 g/cm 3 . 154 Although, the presence of pores may enhance the oxidation of SiC heating elements at elevated temperatures, it is important to bear the thermal shock during the heating/cooling cycles. The oxidation resistance of SiC heating elements can be enhanced by applying a protective coating on its surface, as reported previously.…”

“…SiC heating elements have been used for several years 32,47,[154][155][156][157][158] and different applications of these elements demand specific designs, as schematically shown in Figures 9A and B. A rod-type commercial SiC heating element, which is commonly used in high temperature furnaces, is shown in Figure 9A (reproduced with permission from Ref.…”

Mechanical and electrical properties of 3Y‐TZP/TiSi2 composites sintered at different temperatures

“…The electric heating element is the most widely adopted in the heater of HNB, which refers to the technical application of transforming electric energy into heat energy through resistance. Electric heating elements generally are divided into metal (nickel‐based alloy, iron aluminum alloy, etc.,), non‐metal (SiC, MoSi 2 , ZrO 2 , LaCrO 3 , etc.,), and others (PTC, thick film) heating elements 5–11 . The electric heating elements in HNB have volume effects, including size, shape, and application condition restrictions, which make the resistivity and strength of the current electric heating materials unsuitable.…”

“…Electric heating elements generally are divided into metal (nickel-based alloy, iron aluminum alloy, etc.,), non-metal (SiC, MoSi 2 , ZrO 2 , LaCrO 3 , etc.,), and others (PTC, thick film) heating elements. [5][6][7][8][9][10][11] The electric heating elements in HNB have volume effects, including size, shape, and application condition restrictions, which make the resistivity and strength of the current electric heating materials unsuitable. Consequently, there is an urgent need to synthesize a new heating element composite material that exhibits suitable mechanical and electrical properties, while also meeting the specific requirements of the heating element.…”
