'''Terbiumટર્બિયમ''' ({{IPAc-en|icon|ˈ|t|ɜr|b|i|ə|m}} {{respell|TUR|bee-əm}}) is aએક [[chemicalરાસાયણિક elementતત્વ]] withછે theજેની symbolરાસાયણિક સંજ્ઞા '''Tb''' andઅને [[atomicઅણુ numberક્ર્માંક]] 65૬૫ છે. It is a silvery-white [[Rare earth element|rare earth]] [[metal]] that is [[malleable]], [[ductile]] and soft enough to be cut with a knife. Terbium is never found in nature as a free element, but it is contained in many [[mineral]]s, including [[cerite]], [[gadolinite]], [[monazite]], [[xenotime]] and [[euxenite]].
 
Terbium is used to [[Dopant|dope]] [[calcium fluoride]], calcium [[tungstate]] and [[strontium]] [[molybdate]], materials that are used in [[solid-state device]]s, and as a crystal stabilizer of [[fuel cell]]s which operate at elevated temperatures. As a component of [[Terfenol-D]] (an alloy that expands and contracts when exposed to magnetic fields more than any other alloy), terbium is of use in [[actuator]]s, in naval [[sonar]] systems and in [[sensor]]s.
