Embodiment Construction
[0033] like figure 1 As shown, the present invention is a rare earth thick film circuit controllable electric heating element based on an aluminum alloy substrate, including a substrate and a series of rare earth electronic pastes. The substrate is made of an aluminum alloy substrate, and the series of rare earth electronic pastes are prepared in the form of a thick film circuit. On the aluminum alloy substrate, a dielectric layer 1, a resistance layer 2 and a conductor layer 3 are sequentially arranged from outside to inside. Among them, the series of rare earth electronic pastes are composed of three parts: functional phase, inorganic binder phase, and organic solvent carrier. A dielectric thick film with insulating properties is prepared on the surface of the aluminum alloy substrate, and the rare earth resistor paste and the rare earth electrode paste are prepared on the dielectric film in the form of a thick film circuit. The aluminum alloy contains 2-7% by weight of mag...
