| Abstract |
| The nucleation and crystallization behaviour of basalt glass has been
studied dynamically by small angle neutron scattering (SANS). The
interparticle interference effect shows a pronounced maximum in the
SANS spectra at the growth temperature of 710 C for different
nucleated samples. The number density of particles decreases with the
time of growth and then saturates at longer time. This behaviour is
interpreted as due to the redissolution of the smaller particles as
the larger ones continue to grow with the stabilized number density
in the ripening stage. The process of redissolution of the particles
during growth of the stable nuclei of the basalt glass is discussed. |
