So it is probable that all Dust can be used to make explosives. ^ Yeah, all Dust seems to combust when triggered, and Ruby's sneeze explosion was fire, ice, and lightning.

During RWBY vs ABRN, when Nadir got his legs frozen in ice, that was from Ruby shooting ice Dust, and the bullet striking the Dust caused it to combust into its element. You can hear the Dust "shimmering" sound effect when she does it.
