钽(Ta)是现代冶金中的无名英雄. 1802年由瑞典化学家安德斯·埃克伯格首次发现, this versatile metal has become essential to numerous industries over the years.<\/p>

生钽在自然界中很少出现. Instead, it is typically found in the ore columbite-tantalite (usually referred to as coltan). 纯钽一旦被提取出来,是一种坚硬的蓝灰色有光泽的金属.<\/p>

Since its discovery, tantalum has been used in a number of applications. 在21世纪, 它已成为电子工业的关键元素, 超过75%的电子产品都含有某种形式的钽. 特别是, engineers have been able to take advantage of some of tantalum\u2019s properties to make 电容器 and other components smaller and more efficient.<\/p><\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ \ t \ t \ \ t<\/div>\ n \ t \ t \ \ \ t<\/div>\n\t\t<\/div>\ n \ t \ t \ \ \ t \ \ t\t<\/div>\ n \ t \ t \ \ \ t<\/div>\n\t\t<\/section>\ n \ t \ t \ \ t

Properties of Tantalum<\/h2>\t\t<\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ t \ \ t

\ n \ t \ t \ \ \ t

Tantalum has several unique characteristics that have led to its increased use in the 21st century. It is a highly stable metal that is almost immune to chemical degradation at temperatures lower than 302 \u00b0F (159 \u00b0C). 除了, it exhibits high levels of 腐蚀 resistance when it comes into contact with air and moisture.<\/p>

像大多数金属一样, tantalum forms a thin but dense protective oxide layer (Ta2O5) when exposed to the atmosphere. 这个氧化层牢固地附着在金属表面, acting as a barrier which protects the underlying metal from further 腐蚀.<\/p>

钽属于一类称为难熔金属的金属, 哪些是由它们的耐热性和耐磨性来定义的. It has a melting point of 5,463 \u00b0F (2,996 \u00b0C), the fourth highest of all metals.<\/p>

在机械性能方面, 钽具有很高的延展性, 使其适用于弯曲等工艺, 冲压, 和紧迫. 当与其他金属结合时, it can produce alloys with enhanced strength and higher melting points.<\/p><\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ \ t \ t \ \ t<\/div>\ n \ t \ t \ \ \ t<\/div>\n\t\t<\/div>\ n \ t \ t \ \ \ t \ \ t\t<\/div>\ n \ t \ t \ \ \ t<\/div>\n\t\t<\/section>\ n \ t \ t \ \ t

Tantalum is generally used in applications that require increased heat, 腐蚀, 耐化学性. Below is a list of the commonly available forms of tantalum and their most common uses.<\/p>

  1. Sheet Plate<\/span><\/strong> \u2013 Tantalum\u2019s high melting point makes it ideal for high-temperature applications. 以表格形式, 它通常用于列衬, 船只, 坦克, 热交换器, 真空炉部件. 薄板也可用于防腐包层, 维修, and reinforcement of existing<\/li>
  2. Rod \/ Wire<\/span><\/strong> \u2013 Tantalum is also known for its biocompatibility. In other words, it is a nonirritating element that is not affected by bodily fluids. This property makes tantalum wires a popular material for prosthetic implants and other medical devices. 除了, tantalum wires are commonly used in vacuum furnace heating elements, 氯化器弹簧, 灯泡元件, 化工加工设备.<\/li>
  3. Powder<\/span><\/strong> \u2013 In its powder form, 钽被用来制造电路, 电容器, 和电阻, primarily because its superior capacitance allows it to hold more charge per gram than other materials. 这使得开发更小的电气部件成为可能, 通过扩展, 更小的电气设备.<\/span><\/li>
  4. Tube<\/span><\/strong> \u2013 Because of their heightened resistance to 腐蚀, 钽管常用于化工, 石化, and pharmaceutical industries for the processing of compounds that may weaken or destroy other metals. 列, 栈, and piping are just some of the products constructed from tantalum tubing in these industries.<\/span><\/li>
  5. Strips and Foils<\/span><\/strong> \u2013 Similar to sheets, tantalum strips and foils can be used as liners in vacuum furnaces and heat insulation applications. Thin-gauge tantalum strips can also be deep drawn to manufacture crucibles, 杯, 以及其他惰性实验室设备.<\/span><\/li><\/ol><\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ \ t \ t \ \ t<\/div>\ n \ t \ t \ \ \ t<\/div>\n\t\t<\/div>\ n \ t \ t \ \ \ t \ \ t\t<\/div>\ n \ t \ t \ \ \ t<\/div>\n\t\t<\/section>\ n \ t \ t \ \ t
