Abstract:
     A slag semiconductor resistor is made of such raw materials (Wt. ratio) as water glass as hardening agent (1.15-1.50), sodium fluorosilicate (0.08-0.15), graphite (0-25), slag powder (0.05-1) and slag sand (0.45-2). It can be used to make railway switch heater or starting resistor of electric motor and features low cost and durable use.
