摘　　要：1791年,英国矿物学家格雷戈尔发现钛矿石并意识到一种新元素的存在。至1795年,普鲁士化学家克拉普罗特进一步预言了该元素,并将之正式命名为钛(Titanium)。1910年,美国化学家亨特制取了纯净的钛单质,钛元素的概念正式形成。20世纪20年代以后,钛同位素的发现使人们对钛元素有了新认识,并逐渐形成现代钛元素概念。钛元素概念的发展使人们在科学认知上发生了转变,促进了化学元素观的演进。In 1791,British mineralogist Gregor discovered titanium ore and realized the existence of a new element.By 1795,the Prussian chemist Klaproth had further predicted the existence of the element and officially named it Titanium.In 1910,the American chemist Hunter made pure titanium,and the concept of titanium element was formally formed.After the 1920 s,the discovery of titanium isotopes gave people a new understanding of the concept of titanium,and gradually formed a modern concept of titanium.The development of the concept of titanium element has changed people’s scientific understanding and promoted the evolution of the concept of chemical elements.
