Nickel is a kind of argenteous ferromagnetic metal.Density 8.9 grams per cubic centimters, 1455 ℃ of fusing points.Nickel has magnetic, is the main moiety of many magneticsubstances.Nickel also has good oxidation-resistance, and in air, nickel surface forms the NiO film, can stop further oxidation.Experimental results show that: purity is 99% nickel, iron mold can not take place in 20 years.The resistance to corrosion of nickel is very strong, and especially the resistance to corrosion to caustic alkali is strong, and the corrosion speed in nickel every year is no more than 25 microns in 50% boiling soda lye.The intensity of nickel and plasticity are also fine, can bear various press working.At present, the purposes nickel of nickel is used for making various types of stainless steels, non-retentive alloy and structural alloy steel in a large number.Elements such as nickel and chromium, copper, aluminium, cobalt can be formed refractory alloy, electrical alloy and non-corrosive metal etc.Nichrome (as Ni-Cr20) has high thermotolerance and big resistance, with the pyroelectrics (resistance wire) that it is done, can be used as the electrical heating element of electric furnace, electric iron, electric iron etc., can be 1100 ℃ of following long term operations; Though Ni-Cr9 and Ni-Cr10 thermotolerance are slightly poor, resistance is big, and temperature coefficient of resistance is little, and thermoelectric force is big, is the good material of thermopair.Refractoloy is mainly made the turbine engine turbine disk, combustion chamber and turbine blade etc.Famous " Monel " alloy is the Ni-resist of cupric, iron and manganese, the intensity height, and plasticity is good, and is corrosion-resistant, becomes the manufacturing important materials of electrical equipment, seagoing vessel and medicine equipment.Nickel silicon alloy is often made line, band, rod and is used for electron tube and electrovacuum instrument.In addition, nickel is nickel---cadmium, nickel---main raw of hydrogen battery.In the prior art, though, all be metallic conductor mostly to being that the alloy material of matrix has more research with nickel.For with nickel be matrix the semi-conductor exothermic material research seldom.
Summary of the invention
The objective of the invention is: providing a kind of to society is the alloy material of matrix with nickel, and this alloy material has semi-conductive character, can be used for making various electric heating body.
Technical scheme of the present invention is: a kind of nickel-base alloy semi-conductor exothermic material, contain weight percent: nickel 50-64%, bismuth 21-35%, cobalt 10-23% and titanium 5-12%.
Its optimum proportion is nickel 55%, bismuth 22%, cobalt 15% and titanium 8%.
The resistance value of described semi-conductor nickel-bass alloy material is 0.5 ohm to 50 ohm.
Nickel-base alloy semi-conductor exothermic material of the present invention has good low pressure, can drive work with 10 to 60 volts of voltages of direct current; The nanometer electric heating body made with nickel-base alloy semi-conductor exothermic material has the electric conversion efficiency height, can not produce the safety problem of electric people or electric leakage, use simple, broad-spectrum advantage, be widely used in the making of flexible heating element or hard heating element, as the lifesaving electric warming clothes, the warm cap of electricity, electrically warmed shoe, the warm cap gloves of electricity, open-air electricity warm by, and the army field cook etc.
