Feldspars are a common non-metallic alumino-silicate mineral that have a hardness of 6 on Mohs scale and produce white streaks.
There are broadly three main types: potassium, sodium and calcium rich feldspars. They have the following general chemical formulas:
KAlSi3O8 - NaAlSi3O8 - CaAl2Si2O8
The endmember mineral states are known as K-Feldspar, Albite and Anorthite which are the potassium, sodium and calcium feldspars respectively.
Perhaps you mean feldspar?
Feldspar is the most common rock mineral in the Earth's crust (about 60%).
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
A steel nail can scratch feldspar but not quartz. Feldspar has a hardness of 6 on the Mohs scale, while quartz has a hardness of 7.
Granite contains plagioclase feldspar and potassium feldspar. It really depends on the composition of the magma from which it forms. If the granite has a lot of pink in it, chances are it is potassium feldspar (K-Spar). If it is dominated by white, then the feldspar is probably plag.
Orothoclase Feldspar belong to the silicates group.
The scientific name for feldspar is a group name that encompasses several different minerals. The most common type of feldspar found in Earth's crust is potassium feldspar, which has the scientific name KAlSi3O8.
Feldspar is found in North Carolina primarily in the Spruce Pine Mining District, which is located in the western part of the state. This area is known for producing high-quality feldspar, including both potassium feldspar and plagioclase feldspar. The feldspar from this region is used in various industries such as ceramics, glassmaking, and abrasives.
Feldspar sand is a type of sand that contains a high proportion of feldspar minerals. Feldspar is a group of rock-forming minerals that are commonly found in igneous and metamorphic rocks. Feldspar sand can be used in a variety of applications such as in construction, ceramics, and glassmaking.
microcline is the answer
roughly 70 percent of all feldspar (including aplite) sold or consumed in the United States is in the glass-making industry,
Orthoclase feldspar is 6 on the Mohs scale of mineral hardness.
Feldspar's fracture is brittle
Pegmatite is used for feldspar, sheet mica, beryllium, tantalum niobium, and lithium minerals.
The fracture of feldspar is conchoidal or brittle.
The fracture of feldspar is conchoidal or brittle.
Fluorite is harder than feldspar, so scratching fluorite against feldspar would cause the fluorite to scratch the feldspar. This means the fluorite would leave a mark on the feldspar, showing that fluorite is harder than feldspar.
Feldspar is used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. It makes 60% of the worlds crust and Italy is its main exporter
Feldspar is a mineral found prety mutch anywhere.
