Palladium is a member of the platinum group, and its appearance is similar to platinum, showing the luster of silvery white metal. Its color is relatively transparent, its specific gravity is lighter than platinum, its ductility is strong and its chemical properties are relatively stable. Insoluble in organic acid, cold sulfuric acid or hydrochloric acid, soluble in nitric acid and aqua regia, it is not easy to lose its luster by oxidation under normal circumstances. The element seal of palladium is pd, and the element seal of platinum is pt. The density of 8 kg is lower than that of platinum, and the same cubic centimeter of platinum is heavier than that of 8 kg of palladium. For jewelry of the same size, palladium weighs only half as much as platinum. So the price of palladium is lower.

Now many people like white metal jewelry, and there are many kinds of white metal jewelry on the market. If letters are printed on the gesture, pt stands for platinum and pd stands for palladium. If the lettering on jewelry is vague, it can only be identified by burning. Put the jewelry on the fire for half an hour, platinum and palladium will not melt because of their high melting point, but after Ba Jin is burned, the color will turn black after cooling, and platinum will not.

If you are not at ease, you can put platinum and Ba Jin into strong acid. If it's not platinum or 8 kg, react immediately. Platinum has a high density and will not be easily damaged in friction, so the video made without platinum is very fine, and it is not easy to fall off with platinum inlaid with various gems. Platinum, the natural white metallic luster, is natural, elegant and subtle, and platinum jewelry is also easy to match with all kinds of clothing to create a fashion classic. If it is difficult to identify with naked eyes, white gold, commonly known as platinum, is an alloy, usually marked with 18k. Platinum is a natural white precious metal, and its content will be marked with pt, so just recognize the mark when you buy it.

Although we have this knowledge, if we want to buy these ornaments, we'd better go to some reputable businesses to buy them. This is also a very important point.
