11. Ferroelectric crystals often show several transition temperatures and ferromagnetic crystals. 12. The predicted benefit in superconducting transition temperature was therefore a factor of about 300. 13. LaB 6 is a superconductor with a relatively low transition temperature of 0.45 K. 14. :: Yes, look into the glass transition temperature article first. 15. Polycarbonates have a high glass transition temperature but poor optical properties for fluorescent detection. 16. The specific heat of amorphous materials has characteristic discontinuities at the glass transition temperature . 17. Below the transition temperature displacement of electric charges causes polarisation. 18. These factors influence the polymers crystallinity, melt and glass transition temperatures and molecular weight. 19. Nevertheless, the ? phase usually persists below the transition temperature . 20. Materials are only ferroelectric below their corresponding transition temperature .
