从India供应商批发进口Quartz — FOB条款

Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms (silica dioxide). It is basically one of the most famous and the second most abundant mineral with many uses found on earth. It is a major component of rocks (igneous, metamorphic and sedimentary rocks) and forms in all temperatures.�?�  Quartz in its purest form is clear or white in color but different impurities within the atomic lattice can cause the color to change to purple, pink, brown, black, gray, green, orange, yellow, blue, or red and in some cases, multi-color. There are various varieties of quartz with different uses. The following are the major properties of quartz which makes it one of the most useful naturally occurring� minerals. 1.Some Quartz crystals possess piezoelectric property, which is the ability to generate electric potential when subjected to mechanical stress. 2.Quartz is one of the hardest naturally occurring minerals and hence can not be corroded easily. 3.It has a very high melting point and can withstand critically high temperatures. 4.It is chemically stable and does not react with other chemicals and substances.
