Question

Corundum is _________ mineral of aluminium mineral.
A.Silicate
B.Oxide
C.Double Salt
D.Sulphate

Answer 1

Hint:
Corundum in its unadulterated state is vapid, however the presence of modest quantities of pollution can give an expansive scope of tints to the mineral. Most corundum contains almost 1 percent iron oxide. The mineral promptly climates to different aluminous minerals.

Complete step by step answer:
Corundum is a translucent type of aluminium oxide commonly containing hints of iron, titanium, vanadium and chromium.
It is a stone shaping mineral. It is additionally a naturally transparent material yet can have various tones relying upon the presence of progress metal contaminations in its glasslike structure.
Thus, on the basis of the above explanation we can say that the correct answer to the given question will be option B - Oxide. Corundum is an Oxide mineral of aluminium mineral.
Hence, option B is the correct answer.

ADDITIONAL INFORMATION:
Corundum happens as a mineral in mica schist, gneiss, and a few marbles in transformative rock formations. It likewise happens in low-silica volcanic syenite and nepheline syenite intrusive. Different events are as masses nearby ultramafic intrusive, related with lamprophyre barriers and as huge gems in pegmatites. It normally happens as a detrital mineral in stream and sea shore sands in light of its hardness and protection from enduring. The biggest recorded single precious stone of corundum was estimated around $65cm \times 40cm \times 40cm$ , and weighed $152kg(335lb)$. The record has since been outperformed by certain engineered boules.

Note: Due to corundum's hardness, it can scratch pretty much every other mineral. It is ordinarily utilized as a grating on everything from sandpaper to enormous instruments utilized in machining metals, plastics, and wood.
