Collective selection:铂金需要怎么辨别真假?
珠宝首饰相信大家都比较喜欢,特别是即将步入婚姻殿堂的新人基本都会有购买珠宝首饰的需求。其中,铂金类的饰品属于比较热门的,像是铂金戒指,铂金项链等。那么,怎么辨别铂金首饰的真假呢?

首先,根据我国的相关要求,所有类似产品都必须刻上相应材料的标记。白金标识是Pt,一般标志是Pt950andPt900,这个数字是白金的纯度,即白金含量的千分数。一般来说,铂金的识别方法如下:

1、观色法:纯白金为白色,发光光泽;白色k金为白色,部分米黄色,可以从表面颜色中区分。

2、孙权衡法:通过测试白金密度达到21.45,体积相同的物质的重量,比白金重(19.36)Compared tok白金重(10.45),比银重。

3、熔融方法:铂熔点达到1700℃,远远高于k铂和银。普通火炬不能熔化铂,因此可以确认真伪。铂冷却后颜色不变。

4、标记方法:铂宝石有标准印章。Pt950表示白金纯度为950‰。

5、煤气自然法:把首饰放在拧开的煤气灶燃烧器上,放上几分钟,首饰变红的话,煤气炉就会被点燃,表明这是白金产品。因为铂是催化剂,促进气体和空气中的氧化和散热,能加热铂,使其变红,从而点燃气炉。

6、点试法:在白金宝石的边缘或中间凹陷,用文件将粉末放入过氧化氢瓶中,白金会作为催化剂,分解过氧化氢,释放氧气,还可以上下搅动。
