The small-angle neutron scattering (SANS) technique was used to verify the presence of inhomogeneities of the order of 10-100 nm which were suggested to influence the forming behaviour of container glass. Ternary soda lime glass and multicomponent container glass samples taken during periods of good and bad workability were investigated. The collected intensities show a marked SANS signal only in the case of heat treated ternary glasses, thus suggesting the presence of inhomogeneities between 1 nm and a few hundreds of nanometres in size. No inhomogeneities larger than 1 nm were found in the commercial glasses, regardless of their workability level. The presence of smaller inhomogeneities cannot be excluded.

Abstract
The small-angle neutron scattering (SANS) technique was used to verify the presence of inhomogeneities of the order of 10-100 nm which were suggested to influence the forming behaviour of container glass. Ternary soda lime glass and multicomponent container glass samples taken during periods of good and bad workability were investigated. The collected intensities show a marked SANS signal only in the case of heat treated ternary glasses, thus suggesting the presence of inhomogeneities between 1 nm and a few hundreds of nanometres in size. No inhomogeneities larger than 1 nm were found in the commercial glasses, regardless of their workability level. The presence of smaller inhomogeneities cannot be excluded.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
