Both the fiber core and cladding are typically doped, so that the entire assembly ( core and cladding ) is effectively the same compound ( e . g . an aluminosilicate, germanosilicate, phosphosilicate or borosilicate glass ).

They are manufactured by hydrothermal synthesis of sodium aluminosilicate or another silica source in an autoclave followed by ion exchange with certain cations ( Na +, Li +, Ca 2 +, K +, NH 4 + ).
43.
Aluminosilicate glass or vitroceramic glass, contains 20 % aluminium oxide ( alumina-Al2O3 ) often including calcium oxide, magnesium oxide and boric oxide in relatively small amounts, but with only very small amounts of soda or potash.
44.
In April 2008 the US Naval Medical Research Institute announced the successful use of a kaolinite-derived aluminosilicate infusion in traditional gauze, known commercially as QuikClot Combat Gauze, which is still the hemostat of choice for all branches of the US military.
45.
Andalusite, kyanite, and sillimanite are naturally occurring aluminosilicate minerals that have the composition polymorphs is located at a temperature of 500 �C and a pressure of 0.4 GPa . These three minerals are commonly used as index minerals in metamorphic rocks.
46.
It is made from inorganic aluminosilicate ( Al-Si ) polymer compounds that can utilise 100 % recycled industrial waste ( e . g . fly ash, copper slag ) as the manufacturing inputs resulting in up to 80 % lower carbon dioxide emissions.
47.
The internal components are situated between two panels of aluminosilicate glass, described by Apple as being " chemically strengthened to be 20 times stiffer and 30 times harder than plastic, " theoretically allowing it to be more scratch resistant and durable than the prior models.
48.
Head further noted that this was an aluminosilicate mixed with an abundance of minerals, rare in the United States, and even in the world, that appeared to contain " all the essential minerals and trace elements in a balanced ratio and naturally chelated ".
49.
The " geopolymer " framework results from the cross-linking between these tetrahedra, which leads to a 3-dimensional aluminosilicate network, where the negative charge associated with tetrahedral aluminium is balanced by a small cationic species, most commonly an alkali metal cation.
