I was wondering how I could implement explosion effects in a 3D game. I'm specifically interested in graphical techniques for creating the effects, not the related logic or systems.

Many particles which is actually sprites (So, yes. It is sprites). You might want to see this. It has images that might make you understand how it works.
Though i recall there's also volumetric effects for clouds/mist like in Sonic Ether's mod (The clouds is volumetric and the light too). And also, there's this volumetric explosion in unity, but i don't think that's a true volumetric because i feel like it is using trick to achieve the illusion of volume.
