Question

• Glass is formed by heating sand (silica) with sodium carbonate or calcium carbonate. The
molten liquid cools into a hard and transparent material. The addition of metal oxides
alters the color of the resulting glass.
• Beta-titanium is composed primarily of titanium and heat-treated with a mix of metals
such as aluminum and vanadium. The resulting material has high strength and corrosion
resistance, and is used in dental implants and aircraft parts.
• Iron (II) sulfide is formed by heating metallic iron and elemental sulfur. This results in the
formation of a non-magnetic all-black mineral.
