What are the uses of silicaSiO2 which is 99.77 in the sample of quartz?

The silicate minerals make up the largest and most important class of rock-forming minerals, constituting approximately 90 percent of the crust of the Earth. They are classified based on the structure of their silicate group. Silicate minerals all contain silicon and oxygen.
SILICA is the most abundant mineral found in the crust of the earth. It forms an important constituent of practically all rock-forming minerals. It is found in a variety of forms, as quartz crystals, massive forming hills, quartz sand (silica sand), sandstone, quartzite, tripoli, diatomite, flint, opal, chalcedonic forms like agate, onyx etc., and in with numerous other forms depending upon colour such as purple quartz (amethyst), smoky quartz, yellow quartz or false topaz (citrine), rose quartz and milky quartz. Only pure quartz crystal or rock crystal, untwinned, clear, free from any inclusion, has an important property:
It expands (mechanically) under the influence of electric current and conversely pressure induces a measurable electric current. This property is known as piezoelectricity. The current thus developed is called piezoelectric current.
This property resulting from the asymmetry of its atomic groups makes quartz an effective transducer for coverting electrical energy into mechanical energy and vice-versa. This property in quartz crystals was discovered in 1880-82 by Pierre and Jacques Curie and remained a laboratory curiosity till in 1921 when W.G. Cady, a physicist, discovered that quartz plates could be used to control the frequency of wireless transmission circuits.

Quartz crystals can be used as gems what other more practical uses can quartz crystals have?
Chemically it is Silica - Silicon Dioxide - the main constituent of glass. Quartz is piezo-electric and was used in early sonar transducers, but modern sonar uses synthetic ceramics that are far more sensitive and efficient. (NB: don't be taken in by the purveyors of quartz "healing crystals" who seem to have latched onto this property: their claims for itare pure fraud.) Decoratively, silica is the base part of semi-preciousmineral compounds (metal-silicates).
What is quartz?
Quartz is a naturally occurring silicate mineral composed of silicon dioxide (SiO2). Its hardness is 7 on the Mohs scale and it is in the trigonal crystal system. Quartz possesses a glassy luster and does not exhibit cleavage. The average specific gravity of quartz is 2.62. Quartz can be found in all three rock types, igneous, metamorphic, and sedimentary. Quartz has a white streak, but specimens can be appear colored by impurities or exposure to heat or radiation to hues of white, pink, red, orange, yellow, blue, green, black, smokey, milky, or purple.Quartz is a mineral, chemical composition of silicon dioxide, one of the most common minerals on the planet.
Does the density of a mineral depend on the size of the mineral sample?
No, to tell how hard a mineral is you either have to test it or determine what mineral it is. Testing uses materials of known hardness such as a fingernail, or copper penny, or scratch plate, if the mineral is scratched by whatever you use to test it is softer. Hardness however is not based on size it will be the same for any sample of the same rock no matter what the size because its based on atomic arrangement and bond type.
How is Detection of the abnormal protein rheumatoid factor in the serum found?
There are two ways of measuring Rheumatoid factor in bloodThe Agglutination tests. In this test blood is mixed with minute latex beads that have been covered with human antibodies. If there is RF, the beads clump together or agglutinate. Another agglutination test uses sheep's blood that has had its red blood cells covered with rabbit's antibodies, then mixes the blood being tested with it . If there is RF in the blood sample, the red blood cells clump together. This method is often used to confirm the presence of RF.The Nephelometry test. In this test a blood sample is mixed with antibodies cause the blood to clump if RF is present. A light beam from a laser is directed through the sample containing the mixture and the amount of light blocked by the blood sample is measured. The more clumping that occurs, the cloudier the sample and less light to pass through the tube.

What does it means a quartz watch?
It is a watch that uses an oscillator based on a quartz crystal to electronically keep time. Older watches used gears and an escape mechanism to govern the speed. In a quartz watch, a precision cut piece of quartz is used in part of a circuit to generate a specific frequency. A quartz clock works similarly, but the quartz oscillator is used to control the speed of a motor.
