\nIt is practically free of magnesium, lime and zinc and contains only traces of heavy metals.
\nChemical composition:
\n81% by weight SiO2
\n13,0% by weight of B2O3
\n4% by weight of Na2O
\nThermal properties:
\nCoefficient of linear expansion: 32,5 x10-7 \u00ba C
\nMaximum working temperature : 515 \u00ba C
\nAnnealing temperature: 565 \u00ba C
\nSoftening temperature: 820 \u00ba C
\nSpecific heat: 0,2
\nThermal conductivity (cal\/cm3 \/ \u00ba C \/ sec): 0.0027
\nChemical Resistance:
\nThis glass is highly resistant to water, neutral and acidic solutions, concentrated acids and their mixtures, as well as to
\nchloride, bromine, iodine, and organic solvents. Even during long periods of exposure and at higher temperatures
\nat 100\u00b0C, its chemical resistance exceeds that of most metals and other materials.
\nIt can withstand repeated dry and wet sterilisation without surface deterioration and consequent
\ncontamination. Resistant to attack by various chemicals. Only hydrofluoric acid, very hot phosphoric acid
\nand alkaline solutions with increasing concentration and temperature, increasingly attack the glass surface.<\/p>","protected":false},"excerpt":{"rendered":"
