Fig. 5From: Rounded atelectasis after exposure to refractory ceramic fibres (RCF)Energy dispersive X-ray spectrum of the RCF Sample 1a as example of aluminium silicate fibres. The EDX spectrum shows oxygen, aluminium and silicon peaks resulting from aluminium oxide (Al2O3) and silicon dioxide (SiO2). The Au peak results from a fine layer of gold from the sample preparationBack to article page
