zirconia hollow sphere castable of high frequency electric furnace

Development of waste derived nano-lakargiite bonded high

 · The corrosion of the castable has mainly happened via dissolution of present components in the castable into the molten glass. Alumina particles have more propensities to dissolve in a glassy matrix. Zirconia phases have built an effective barrier in the interfacial zone and prevented the transportation of melted glass into the pores .

Synthesis and Applications of Hollow Particles

Tiny hollow spheres used as piezoelectric sensor and actuator manifested an improved resolution and high powder density. Hydrostatic coefficient for the hollow sphere transducer were 1–2 orders of magnitude larger than those for bulk PZT and the hydrophone figure of merit (FOM) was three orders of magnitude higher than that of bulk PZT.

Refractories and Classification of RefractoriesIspatGuru

 · Zirconia refractoriesIn zirconia refractories main constituent of the refractory is zirconium oxide (ZrO2). Zirconia refractories are useful as high temperature construction materials. They tend to be used in applications where temperatures are above 1900 deg C such as casting nozzles and gates crucibles furnace liners and kilns.
