The physical properties of this chemical are below: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0; (5)Exact Mass: 105.903483; (6)MonoIsotopic Mass: 105.903483; (7)Heavy Atom Count: 1; (8)Covalently-Bonded Unit Count: 1.

The production method of this chemical is below: Prepare the residue of drawing nickel (Ni) and copper (Cu) and then add aqua regia to extract, filter; Next add ammonia and muriatic acid into the filter liquor to have the reaction and then have the ammonium chloropalladate sediment; Then have the refining and filtering and then restore the ammonium chloropalladate with hydrogen, and finally you could get the 99.95% palladium products.

As to its usage, it is widely applied in many ways. It could be used in the industry of electric instrument, chemical industry and precision alloy; It could also be used in producing catalytic agent like asbestos, undercurrent adherent point, printed circuit, dental materials and surgical instrument.

When you are using this chemical, you should be very cautious. For one thing, it is irritant to eyes, respiratory system and skin and may cause inflammation to the skin or other mucous membranes. And it may even have risk of serious damage to the eyes. For another thing, it is toxic which may at low levels cause damage to health. This chemical may cause harm to the unborn child, and with the danger of cumulative effects, it will have limited evidence of a carcinogenic effect. In addition, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source. And it has a very low flash point or evolve highly flammable gases in contact with water.?

Due to so many dangers, you could take the different measures to deal with different cases. Wear suitable protective clothing, gloves and eye/face protection and avoid contacting with skin and eyes . If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Then avoid exposure - obtain special instructions before use and remember not to breathe dust.
