Basalt (UK: / b s l t,-l t /; US: / b s l t, b e s l t /) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon.More than 90% of all volcanic rock on Earth is basalt. Aluminium oxide is a thermally unstable and insoluble compound that occurs naturally in various minerals such as corundum, a crystalline variant of the oxide, and bauxite, which is considered as its principal aluminium ore [1]. It is a white, water-insoluble solid, although mineral forms can appear black. FDA claims that TiO 2 may be safely used as a colour additive for colouring foods in oxidative burst and nitric oxide production. Viridian. IDM Members' meetings for 2022 will be held from 12h45 to 14h30.A zoom link or venue to be sent out before the time..
