Fluorescent Minerals Fluorite typically glows a blue-violet color under shortwave and longwave light. Some specimens are known to glow a cream or white color. Many specimens do not fluoresce. Fluorescence in fluorite is thought to be caused by the presence of yttrium, europium, samarium [3] or organic material as activators.

- Apatite is a group of phosphate minerals which includes hydroxyl-apatite, fluor-apatite and chlor-apatite. Apatite is the most common type of phosphate in the world and it is the main source for phosphorus, a chemical essential to bioenergetics and photosynthesis.Apatite is composed of calcium phosphate, which is the same material that makes up teeth and bones.lthough apatite is a very common mineral, transparent gemstone-quality apatite is extremely rare. Despite apatite being the defining mineral for 5 on the Mohs scale of mineral hardness, it remains virtually unknown to most consumers and is seldom found in jewelry stores.

Molybdenum Fluoride is a mineral that occurs naturally in all water sources, even the oceans. The fluoride ion comes from the element fluorine. Fluorine, the 17th most abundant element in the earth's crust, is never encountered in its free state in nature. It exists only in combination with other elements as a fluoride compound.

Rhyolite Rhyolite is an igneous rock in the class designated as felsic rock. This class of rock crystallizes from silicate minerals at relatively low temperatures and with relatively a high percentage of silica . It is at the low temperature extreme of the Bowen reaction series. Rhyolite has a composition similar to granite but has a much smaller grain size. It is composed of the light-colored silicates and is usually buff to pink in color. Occasionally it is light gray. In texture it is classified as aphanitic.

- The most common fluorine minerals are fluorite, fluorspar and cryolite, but it is also rather widely distributed in other minerals. It is the 13th most common element in the Earth’s crust. Fluorine is made by the electrolysis of a solution of potassium hydrogendifluoride (KHF2) in anhydrous hydrofluoric acid.

Hydroxylapatite Carbonated calcium-deficient hydroxylapatite is the main mineral of which dental enamel and dentin are composed. Hydroxylapatite crystals are also found in the small calcifications (within the pineal gland and other structures) known as corpora arenacea or 'brain sand'.ydroxylapatite is the hydroxyl endmember of the complex apatite group. The OH − ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system.

- Some believe that baseball originated from the sport of cricket. The first known documentation of cricket being played in England is from the 16th century. Cricket is played in a somewhat similar manner to baseball.A batter attempts to hit a ball thrown by the bowler on the opposing team.o maybe the “idea” of baseball originated in England; however it was perfected in the States. As an electronic baseball scoreboards manufacturer, we here at Electro-Mech understand the importance of covering a variety of sports material, like the history of the game of baseball that this article covered.

Fluorite Facts Fluorite, also called fluorspar, is a mineral made up of calcium and fluoride or calcium fluoride. It can come in every single color on the color spectrum. Fluorite dates back at least to the 1500s and has many industrial uses. Its crystals are cubic shaped. Interesting Fluorite Facts: Pure fluorite is colorless.

Corundum Some emery is a mix of corundum and other substances, and the mix is less abrasive, with an average Mohs hardness of 8.0. In addition to its hardness, corundum is unusual for its density of 4.02 g/cm 3, which is very high for a transparent mineral composed of the low-atomic mass elements aluminium and oxygen.orundum from Brazil, size about 2 cm × 3 cm (0.8 in × 1 in). Corundum occurs as a mineral in mica schist, gneiss, and some marbles in metamorphic terranes. It also occurs in low silica igneous syenite and nepheline syenite intrusives.

Minerals Pyrite (FeS 2 ) is a mineral that contains a sulfide ion as its anion. Gypsum [CaSO 4 –2(H 2 O)] contains the polyatomic anion known as sulfate (SO 4 2− ) as well as two waters of hydration (water molecules that are part of the crystalline structure). It has been noted that the chemical composition of minerals could vary within specified limits. This phenomenon is known as solid solution.

Apatite Fluoridated water allows exchange in the teeth of fluoride ions for hydroxyl groups in apatite. Similarly, toothpaste typically contains a source of fluoride anions (e.g. sodium fluoride, sodium monofluorophosphate). Too much fluoride results in dental fluorosis and/or skeletal fluorosis.

Fluoride The soft, colorful mineral is found worldwide. Seawater fluoride levels are usually in the range of 0.86 to 1.4 mg/L, and average 1.1 mg/L. For comparison, chloride concentration in seawater is about 19 g/L. The low concentration of fluoride reflects the insolubility of the alkaline earth fluorides, e.g., CaF 2.
