Question

- using scientific seto explain the refrence article the of Please rite o following article o question and w high have i Explain on some coramic materials have thermal conductivly but at the same time low electrical conductivity z- commut defendence on on the the electrical and thermal conductinty temportere for these materials. notes o-- please write the refrence of answa as scientific orlick - hard writting clear words line.

Answer 1

Gillen- > Thermal conductivity means how easily heat can be transferred through a Material Themal Cunductivity of Pine Ceramics is generated by the moveinent of electrons and the transferring of Lattice libractions from I unit cell to other But if electriccel rasistance is ineans that' there is no free electrons to pass electricity in that case lattice vibration is high that implice electr Thermal candluciuity will be high while It has low electrical conductity due to no free electrons . In ceramics we hause Ionic covalent bondling which cloes not have free electrons so it has dow the electrical conductivity 10 electrical concluctivity is inore when tempel cracture increases as velocities at electrons increases their they collide nove often with each other and lattice librations increases so rasistance decreases Thermal conductivity decreases as tempera cture increases As of emperacture increases indecular

vibration increases thus increasing mean free 1 of molecules so theal abstrut the flow of electrons so affernal conductivity decreases.
