\n\u00c9 praticamente livre de magn\u00e9sio, cal e zinco e cont\u00e9m apenas vest\u00edgios de metais pesados.
\nComposi\u00e7\u00e3o qu\u00edmica:
\n81% por peso SiO2
\n13,0% em peso de B2O3
\n4% na wt Na2O
\nPropriedades t\u00e9rmicas:
\nCoeficiente de expans\u00e3o linear: 32,5 x10-7 \u00ba C
\nTemperatura m\u00e1xima de trabalho : 515 \u00ba C
\nTemperatura de recozimento: 565 \u00ba C
\nTemperatura de amolecimento: 820 \u00ba C
\nCalor espec\u00edfico: 0,2
\nCondutividade t\u00e9rmica (cal\/cm3 \/ \u00ba C \/ seg): 0,0027
\nResist\u00eancia qu\u00edmica:
\nEste vidro \u00e9 altamente resistente \u00e0 \u00e1gua, solu\u00e7\u00f5es neutras e \u00e1cidas, \u00e1cidos concentrados e suas misturas, bem como a
\ncloreto, bromo, iodo, e solventes org\u00e2nicos. Mesmo durante longos per\u00edodos de exposi\u00e7\u00e3o e a temperaturas mais elevadas
\na 100\u00b0C, a sua resist\u00eancia qu\u00edmica excede a da maioria dos metais e outros materiais.
\nPode resistir \u00e0 esteriliza\u00e7\u00e3o repetida a seco e a h\u00famido sem deteriora\u00e7\u00e3o da superf\u00edcie e consequente
\ncontamina\u00e7\u00e3o. Resistente ao ataque de v\u00e1rios produtos qu\u00edmicos. Apenas \u00e1cido fluor\u00eddrico, \u00e1cido fosf\u00f3rico muito quente
\ne solu\u00e7\u00f5es alcalinas com concentra\u00e7\u00e3o e temperatura crescentes, atacam cada vez mais a superf\u00edcie do vidro.<\/p>","protected":false},"excerpt":{"rendered":"
