Abstract: A felted mass of selenium fibres is obtained by spraying molten selenium by air or gas pressure through one or more nozzles. The selenium may be melted in an electrically heated tank thermostatically controlled at a temperature of above 220 DEG C., the molten selenium being sprayed through a multiplicity of nozzles on to a horizontal travelling band. The felt so formed may be intercepted by a fixed horizontal platform and stored in rolls.
