Scientific paper

It is shown that in a protostellar cloud at different stages of its contraction dust particles with opposite signs of electrical charge can exist. If fast (nonthermal) electrons are present in the cloud, these dust particles coagulate rapidly, forming solid grains of size much larger than the mean one, typical for the interstellar medium, and having inhomogeneous chemical composition.
