Corundum grinding wheels are suitable for grinding materials such as Inconel 718.
An actual conundrum was evidenced in thousands of dream fragments, in which
corundum was a mere particle, but when connected to a blizzard of other particles, it led to a quantum paradigm, a new order of dreaming-waking consciousness.
For the ratio of 10 wt% rice husk ash, only the
corundum ([A.sub.2][O.sub.3]) phase was detected because the ratio of Si[O.sub.2] in the rice husk ash was not sufficient to react with [Al.sub.2][O.sub.3] for production or transformation into another ceramic phase like cristobalite (Si[O.sub.2]) and mullite (3[Al.sub.2][O.sub.3] x 2Si[O.sub.2]); this is evident in Figure 7.
Further XRD analysis predicts almost 79.93%
corundum in sample C with closed pack rhombohedral system.
At 10 min of solar radiation exposure, temperature was nearly 900[degrees]C, and the XRD pattern of sample (S10) shows diffraction peaks assigned to the hkl reflections reported in the JCPDS file 1-089-7717 for the [alpha]-[Al.sub.2][O.sub.3] (
corundum), along with the previous one corresponding to [gamma]-[Al.sub.2][O.sub.3].
Impact bricks were laid in the lashed area and then the
corundum castable was poured.
A similar tendency variation of tribological behaviour of the studied material against
corundum was exhibited, in reference [17], in which the highly pure [Ti.sub.3]Si[C.sub.2] sliding dryly against the low carbon steel.

El rubi, ademas de ser una gema preciosa en su forma de
corundum (forma de mineral de la que se derivan los zafiros y rubies), es una sustancia muy util para estudios opticos y puede ser sintetizada; su estructura es muy simple para estudiar y ademas los iones de cromo tienen propiedades magneticas y opticas que se utilizan facilmente.
For instance, Cleopatra's favourite stone was the emerald, Queen Victoria started wearing 'Jet' jewellery after the death of her husband, Helen of Troy is said to have worn star
corundum, which is a powerful love charm.
the Keystone Trappe Rock quarry at Cornog (exquisite small specimens of Alpine-type cleft minerals), Brinton's quarry at Darlington's Corners (the world's best large clinochlore crystals), the Poorhouse quarry, West Bradford Township (excellent microcline),
Corundum Hill, Newlin Township (good
corundum and superb diaspore crystals), the fields around Parkesburg where line rutile crystals may still be found loose in the soil.
