In doing ruthenium refining technology, refining the program to develop the company ruthenium, ruthenium which crude molten operating quite dangerous, but also increase the company ago due to alkali fusion crude ruthenium aroused shocking explosions, so the alkali fusion has bogey Chan, In order to prevent this kind of thing from happening again, I have established a strict melting procedure and made a 2000 gram crude melting demonstration.

Methods as below:

1) Wet the rough water of about 100 mesh and spread it in the steel tank. The thickness is about 1 cm,

2) Add 1 part by volume of caustic soda first, then add 2 parts by weight of sodium peroxide and mix well, then add the remaining three-fifths of caustic soda and all the sodium peroxide to mix.

3) Put the remaining caustic soda into the iron crucible to melt it on the furnace, slowly add the evenly stirred material, add a small amount to make it melt into a liquid, and then add a small amount when agitating, and then add a small amount until the material is added. After the end, raise the fire temperature to about 700 degrees for 3 hours.

4) Observe the melt when the melt is red and bright, and the furnace is turned off, and the cooling is entered into the subsequent procedure.
