概况钛发现于1790年,经过了160年以后,于二十世纪五十年代初才步入工业生产。钛矿分布广、储量大,按元素在地壳中储量计算,钛占地壳重量的0.61％,在所有的金属元素中占第七位,仅次于铝、铁、钙、钠、钾、镁的含量,比常见的铜、镍、铅、锌的总和还要多十几倍。所以,钛原料的供应不会发生严重短缺,决不会象铬、钴、镍和其他战略金属那样缺少。钛的矿物有70多种,目前用来提取海绵
Overview Titanium was discovered in 1790 and after 160 years it entered industrial production in the early 1950s. Titanium is widely distributed and reserves are large. According to the elemental reserves in the crust, titanium accounts for 0.61% of the weight of the crust, and occupies the seventh place among all metal elements, second only to aluminum, iron, calcium, sodium, potassium and magnesium Content, more than a dozen times more than the sum of common copper, nickel, lead and zinc. Therefore, the supply of titanium raw materials will not be a serious shortage, and never like the lack of chromium, cobalt, nickel and other strategic metals. More than 70 types of titanium minerals are currently used to extract sponges
