Melting of glass

There are large-scale operations using direct-heat resistance furnaces. These are mainly in melting bulk materials where the Hquid material serves as a uniform resistor. The material is contained in a cmcible of fixed dimensions which, coupled with a given resistivity of the material, fixes the total resistance within reasonable limits. The most common appHcation for this type of direct-heat electric resistance furnace is the melting of glass (qv) and arc furnaces for the melting of steel (qv). [Pg.138]

Regardless of the method and plant employed for the melting of glass, it always involves the following processes taking place parallel or in sequence ... [Pg.48]

During the melting of glasses of the system Na20 —B2O3 —Si02, sodium borates form from 500 °C upwards, then follow borosilicates and the dissolution stage starts from 900 C upwards. [Pg.49]

Without making substantial simplifying assumptions, it has so far been impossible to describe exactly the process of dissolution taking place in the melting of glass, in particular because of the complex hydrodynamic conditions which are difficult to define. [Pg.268]

Unconventional melting of glasses includes splat cooling, which is used extensively to produce amorphous metals laser spin melting, which can produce 100-800 pm... [Pg.242]

After the batch has been thoroughly mixed, it is melted at high temperature to form a homogeneous liquid melt. For small-scale melting of glass the batch will be placed in a crucible. For glass-melting experiments in the laboratory it is common to use Pt, or a Pt alloy such as Pt-5% Au or Pt-20% Rh crucibles. [Pg.466]

Differences between surface and volume stages of the crystallization and melting of glasses were revealed by means of DSA. The results obtained for the systems Pb0-Si02 and Ge-Se-Te are presented in [27,28]. [Pg.162]

Melting of glass or a glass transition is a second-order transition, which is described by the Vogel-Fulcher law [103] ... [Pg.119]
