Hot gas atomized melts - potentials for thermal spray powders
© OTH Amberg-Weiden (5/2005)
The atomization of molten materials using hot gases has advantages in comparison to the conventional gas atomization techniques. Some of these advantages favour the hot gas technology for the powder production for thermal spraying. Firstly, a considerably higher output of fine powder, in particular within the important particle size range between 5 and 30 µm, is a result of hot (inert) gas atomization. The reasons are the strongly increased gas exit velocity and the higher overall temperatures inside the interaction zone of the gas and the melt droplets.

The mass balances in a selected Chilean cement production facility indicate that the use of contaminated volcanic soil as an alternative raw material can be an interesting alternative for the management of these materials.
