Effects of spraying plants with suspensions of inert dusts*
Annals of Applied Biology, 1969 SUMMARYIn an examination of possible harmful effects to plants caused by spraying leaves with inert dust suspensions it was shown that Stockalite (kaolin), talc, silica or Tiona W.D. (titanium oxide), suspended in water and sprayed on excised leaves of three species, significantly (P≯ 0·05) increased water loss and penetration of gaseous ammonia; these

Experimental Investigation on Inerting Mechanism of Dust Explosion
Procedia Engineering, 2012 Systematic experiments were carried out on explosions of coal dust-inertant mixtures. Explosion severity was gained by using Siwek 20 L vessel and factors strongly influencing inerting effectiveness, such as deflagration mechanism and inertant composition were taken into account.
