Aluminium resistance alloy for low temperatures - with temperature coefficient of resistance adjusted by addition of magnetic metalsThe temp. coefft. of resistance is adjustable at low temps. continuously between a positive or negative value by the addn. of a magnetic metal and/or annealing at an...
By adding a compensating layer of SiO2 with an appropriate thickness, a Lamb wave resonator based on a stack of AlN and SiO2 layers can achieve a zero first-order temperature coefficient of frequency (TCF). Using a composite membrane consisting of 1 microm AlN and 0.83 microm SiO2, a Lamb ...
functional material of resistive pastes has a significant influence on the specific resistance and temperature coefficient of resistance of thick-film resistors... MD Smolin,VN Fedorov,VG Grebenkina,... - 《Soviet Powder Metallurgy & Metal Ceramics》 被引量: 4发表: 1987年 A study of some produc...
Using the thermal expansion coefficient(αT)and the Anderson-Grüneisen parameter(δT)definition expression,we obtained a relationship for the volume dependence of the thermal expansion and the bulk modulus(BT).We have calculated the thermal expansion and the bulk modulus with this relationship for Mg...

3.5.2 Positive temperature coefficient (PTC) Positive temperature coefficient (PTC) is the kind of protective device whose resistivity increases with temperature. The primary function of this device is to protect Lithium-ion battery against high currents due to external short-circuit or overcurrent and...
Starting from the three-dimensional model for grain boundary conductivity theoretical expressions for the conductivity, its TCR and the Hall coefficient are derived. In the limit of a small magnetic field the relative grain boundary Hall coefficient is approximately equal to the product of the relative...
