Abstract: 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 ar… Show more

“…The thermodynamics of crystallization are also of critical concern, as quantified by the liquidus temperature of the system (Wallenberger and Smrcek, 2010). Liquidus temperature and phase equilibrium diagrams are of vital importance for all aspects of glass formation; however, there is currently no predictive model derived from fundamental physical considerations.…”

“…To obtain a dense microstructure by sintering the glass powder, approximately 10 6 dPa s is normally required, as described in Fig. 1 [21], its corresponding temperature lies in the range of 1080-1120 1C. The corresponding viscosity of LPWG to the above sintering range of 1100-1200 1C for the sanitary ware approaches to 10 5 -10 6 dPa s. Therefore, it can be expected that LPGW is a strong candidate to be a substitute for feldspar.…”

“…The liquidus temperature, T Liq , is defined as the highest temperature at which crystals are thermodynamically stable in contact with the melt; both the liquid and the solid state are in equilibrium at this temperature and all crystals dissolve above it . Therefore, the liquidus temperature is a very important parameter as in an industrial glass melt for commercial production, crystallization should not occur within the temperature range used for forming the glass, especially with respect to glass fiber production . In multicomponent glass‐forming systems, below T Liq , but still above the solidus temperature, crystals form within a few hours and remain in equilibrium with a certain quantity of liquid .…”

“…Thus, also the production costs are affected as T Liq generally provides a clear indication of the minimum possible melting and forming temperature . In particular in multicomponent systems, small compositional changes can cause dramatic changes in the liquidus temperature …”
