| The toughness, strength, and translucence of porcelain arise mainly from the formation of glass and the mineral mullite within the fired body at these high temperatures. |
| The formation of primary mullite at doses above four percent may be responsible for the increase in strength observed thereby. |
| For fly ash, peaks of quartz and mullite dominate the XRD spectra. |
| The company produces very high-grade industrial ceramics including alumina, cordierite, mullite, and zirconia, etc. |
| The studies are carried out using the production waste of mineral or mullite wool, fly ash, crushed glass, waste of paper manufacturing, etc. |
| Occupational exposure and analysis of microcrystalline cristobalite in mullite. |
