Mineral Resource of the Month: Cultured Quartz Crystal

Cultured quartz crystal, also known as electronic-grade quartz crystal, is single-crystal quartz that has properties that make it uniquely useful in electronic circuits for precise filtration, frequency control and timing for consumer and military use. Common uses for cultured quartz crystal include aerospace hardware, commercial and military navigational instruments, computers, clocks, games, television receivers, toys and communications equipment like cell phones.

Mineral Resource of the Month: Graphite

Graphite, a grayish black opaque mineral with a metallic luster, is one of four forms of pure crystalline carbon (the others are carbon nanotubes, diamonds and fullerenes). It is one of the softest minerals and it exhibits perfect basal (one-plane) cleavage. Graphite is the most electrically and thermally conductive of the nonmetals, and it is chemically inert.

Mineral Resource of the Month: Antimony

Today, antimony is used in everything from flame retardants, batteries, ceramics and glass. About 40 percent of the primary antimony consumed in the United States goes into flame retardants, chemicals that when applied to or coated on a variety of materials (such as aircraft, automotive seat covers and children’s clothing and toys) make them more resistant to combustion. The remainder is used primarily in glass for television picture tubes and computer monitors, in pigments, in stabilizers and catalysts for plastics, and in ammunition, cable coverings, friction bearings, lead-acid batteries, pewter and solders.
