银和黄金一样,是一种应用历史十分悠久的贵金属,人类开始开采白银要上溯到4000多年前。由于当时银的开采量很小,使得它的价值比金还贵。公元前14～16世纪埃及王朝的法典规定的银价为金的2倍,甚至到了公元17世纪的日本,政府规定金、银的价值还是相等的。普通老百姓针对白银的概念大多集中在银元、银首饰、银餐具等方面。其实,除此之外,由于白银特有的物理化学特性,它还是重要的工业原料,广泛应用于电子电气、感光材料、医药化工、消毒抗菌、环保、白银饰品及制品等领域。随着电子工业,航空工业,电力工业的大发展,近年来,白银的工业需求正稳步快速增长。
Like gold, silver is a precious metal with a long history of application. Human beings began to mine silver dating back 4000 years ago. Due to the small amount of silver mining at the time, it was worth more than gold. From the 14th to the 16th century BC, the Egyptian dynastic code stipulated that the price of silver was twice that of gold, even to the 17th century Japan. The government stipulated that the value of gold and silver would be equal. Ordinary people are mostly focused on the concept of silver in the silver dollar, silver jewelry, silver cutlery and so on. In fact, in addition, due to the unique physical and chemical characteristics of silver, it is also an important industrial raw materials, widely used in electronic and electrical, photographic materials, pharmaceutical and chemical, disinfection and antibacterial, environmental protection, silver jewelry and products and other fields. With the great development of the electronics industry, aviation industry and power industry, the industrial demand for silver is steadily growing rapidly in recent years.
