Sodium feldspar is a glassy crystal of the triclinic system, generally colorless, white, yellow, red or black, and is a type of feldspar. Albite is a framework silicate structure with a specific gravity of 2.62 and a Mohs hardness of 6 – 6.5. The content of anorthite in alumina-magnesia-carbon bricks is less than 10%. Albite is a sodium mineral of the plagioclase solid solution series, common in pegmatites and granites, and was first discovered in Sweden in 1815.
Sodium feldspar is a kind of feldspar, which is a common feldspar mineral and is a sodium aluminosilicate. Albite is generally a glassy crystal, which can be colorless or white, yellow, red, green or black. It is the raw material for making glass and ceramics. Albite is found in many rocks, and such minerals are called rock-forming minerals. Sodium feldspar is mainly used in the manufacture of ceramics, soap, ceramic tiles, floor tiles, glass, abrasive abrasives, etc. It is mainly used in glazes on ceramics.
Albite, a common feldspar mineral, is sodium aluminosilicate (NaAlSi3O8). Common in pegmatites and felsic igneous rocks such as granite, also in low-grade metamorphic rocks, and in some sedimentary rocks as authigenic albite. Albite usually forms brittle glassy crystals of various colors. It can be used to make glass and ceramics, but its main significance is that it is a rock-forming mineral.
Albite is a sodium terminal mineral of plagioclase solid solution series and alkaline feldspar series. It has a tripod-like structure, and silicon and aluminum are tetrahedrally coordinated to form larger vacancies (ie, lattice positions), which are mainly occupied by cationic sodium. Although all silicon and aluminum atoms occupy tetrahedral positions in this structure, the specifics of their positions vary. The distribution of silicon and aluminum atoms is highly ordered at low temperature, but at a high temperature of about 1100°C, the distribution of atoms is much more disordered.
