MELTING BEHAVIOUR OF FELDSPAR PORCELAIN GLAZES

feldspar porcelain, must take into account the data provided by hot-stage microscopy. This can be done by selecting the compositions having the melting temperature (point of minimum base contact area with the substrate) above ~ 1250oC and the final stage of melting (the end of melting) in the range 1360-

THE MELTING RELATIONS OF POTASH FELDSPAR, SODA

The soda feldspar‐flint mixtures were more refractory than were those of the potash feldspar series. At least 20% flint variation with potash feldspar will show no change in P.C.E. values and at least 10% with the soda feldspar showing the unreliability of P.C.E. to indicate the amount of the quartz content.

What is Feldspar? - Industrial Minerals Association ...

Glass: Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. The alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs. Ceramics: In the manufacture of ...

Neutralization of cement-asbestos waste by melting in

01/11/2017  Two materials, i.e. sodium carbonate (soda) and potassium feldspar, were selected for the test of cement-asbestos waste melting due to their relatively high efficiency, availability of raw materials and absence of hazardous substance formation during high-temperature treatment. The assumed ratio of fluxes was 85:10:5 (cement-asbestos:soda:feldspar).
