palladium in nitric

[arthur kierski]

for every 1liter of hno3 containing pd,one have to dilute with water to 2liters ----after this i add 200 to 300cc of 5% sodium hypochlorite solution-----the solution becames red and to this reddish solution i add 100 to 200grams of nh4cl powder and stir a lot----red palladium salt is formed (as it forms with naclo3)----after this i filtrate the red powder and if the solution is green , all the pd is out as red salt---if the solution continues red ,you still have pd in the filtrate--------that is the way i do -Teclus

Arthur Hello,


Thanks again, I remain indebted and I hope that I help you someday.

Oh yes. We've analysed alot of them. They are usually 4-5% Pd per weight. Sometimes they have Pt about 0,3-0,4%.
KM5 (green ones) are more valuable than KM6 (orange, red and yellow).
BTW. What catalog are you talking about? And what Mil. pins with more thn 7,5 % do you mean?

Dimitry Hello,

This catalog is constructed based on technical datas of russian producers of electronic components. In this catalog you can find IC's, transistors, diodes, capacitors, resistors, potentiometers, connectors, even electronic tubes. Quantities are expressed in grams of metal per 1000 pieces of parts, unused.These metals are: Au, Ag, Pt, Pd, Ru and Ta.Even if it is in russian, the catalog may be useful for anyone, at least for comparing similar parts produced in the West Europe or in USA.
You will find there very many connectors too, and you will realize wich ones have more than 7,5%.

Enjoy!

thanks for catalog can you tell us what those words mean, :?:

thanks for catalog can you tell us what those words mean, :?:

The 7 columns of the table, from left to right:
type of parts ... Au ... Ag... Pt... Pd ... Ru... Ta

from page 1 to 58 are IC's
58-105 are diodes, transistors, thyristors, stabilitron ....
105-111 are capacitors
111-136 are resistors, potentiometers
136-175 are conectors and switches
175-181 are quartz resonator and filters, transformers, delay lines
181-191 are tubes/valves(electronic tubes)

Here is some links:
http://www.rustran.com (or you can choose any translator)
and
http://www.google.ro/imgres?imgurl=http://linguistica.insite.com.br/images/russian-alphabet.gif&imgrefurl=http://linguistica.insite.com.br/cgi-bin/russian&h=842&w=484&sz=13&tbnid=qEks32h8ZI2JZM:&tbnh=145&tbnw=83&prev=/images%3Fq%3Drussian%2Balphabet&hl=ro&usg

I attached this catalog for Dimitry(he asked me), but I thought that might be useful for everybody -at least as a reference, to compare it with not/non Russian electronic parts-
of course, with a little(minimum) search job, and maybe with a little kindness....
In this catalog the numbers are more important than the words, for example when you realize that in 1000 pieces of connectors can be over 2 kg of gold...
...anyway If is not interesting for someone else too, then I can delete it.

thanks ,maybe I should try and learn your language, at least gold and silver first. How do you guys who dont speak english do this?

 

[SapunovDmitry]

Золото=gold.
Серебро=silver.
Платина=platinum.
Палладий=palladium.

This was your first russian language lesson.
Congratulations.))))

thanks I printed it out for reference.

Can you reupload or send it to me via PM ? PLEASE!!
