The Liquidus Temperature; Its Critical Role in Glass Manufacturing

The liquidus temperature plays an important role in the manufacture of fiberglass and glass melts and in the design of new energy-saving commercial compositions, which must be formulated to be crystallization resistant, possess a lower operating temperature and require less energy than incumbent commercial compositions

Scholarcy highlights

  • The liquidus temperature plays an important role in the manufacture of fiberglass and glass melts and in the design of new energy-saving commercial compositions, which must be formulated to be crystallization resistant, possess a lower operating temperature and require less energy than incumbent commercial compositions
  • In the manufacture of glass melts and glasses, the temperature at the furnace exit must be above the liquidus temperature to avoid crystallization and many operations beyond the furnace exit are carried out below the liquidus temperature
  • This paper establishes the relationship between liquidus temperature and operating temperatures in various process steps and analyzes the parameters, which are required for the manufacture of new and more energy-saving variants
