By following the wet chemical route the size of the particle would be obtained in the nano range and further due to large number of small grain boundaries with large number of grain boundaries the electrical resistivity gets increased.

What is ferrox cubes?
It is one of the soft magnetic material and it is also a ferrite. It has a square hysterisis loop.These have high permeability and high resistivity. They are used in switching circuits and in matrix storage and shift resisters of computers.Eg:Magnesium-Manganese ferrite(50%MgO+50%MnO)-Fe2O3)
Do wires that have high resistivity have high conductivity also?
No. In fact it is the opposite. Conductivity is the reciprocal of resistivity so a high resistivity means low conductivity. peace.
Does alumina become conductive at high temperatures?
Alumina is a good electrical insulator; at high temperatures the resistivity is smaller than the resistivity at room temperature.
Is resistivity of a good conductor high or low?
It is Low
Why is the resistivity of a potentiometer high?
Because you touch yourself at night.
What periodic table element is used in toasters?
From what I can tell, there are actually 3 of them... Nickel (Ni), Chromium (Cr), and Iron (Fe). The three are combined in certain percentages to make an allow called "Nichrome", as it has high electrical resistivity, a high melting point, and won't oxidize (or rust) at high temperatures.
What property does the metal tungsten on an incandescent light bulb have?
it have high resistivity as well as high melting point. So due to high resistivity collision of moving electrons are taken place. It emits radiation which is appear as light.
For small size high frequency coil most common core material is?
ferrite.
Is metal low conductivity?
No, metals have high conductivity but has low resistivity.
Is it true that a material with high resistivity is a good conductor?
No. It is not true. It is false.
What is DP steel?
dual phase steel is a high strength steel that has a ferrite and martensitic microstructure
How do you convert conductivity to resistivity?
Conductivity is a measure of the ability of a substance to conduct electricity. Resistivity is a measure of how strongly a substance resists the flow of an electric current. So conductivity and resistivity are opposed to each other. A good conductor like copper has a low resistivity, and a good insulator like glass has a low conductivity and a high resistivity. Mathematically, conductivity and resistivity are inverses of each other, so it is quite easy to convert conductivity to resistance.
