tioata borosilicateo se ituaiga o mea tioata ma le maualuga o le boron content, o loʻo faʻatusalia e oloa eseese mai tagata gaosi oloa eseese.Faatasi ai ma i latou, o le Schott Glass's Borofloat33® o se tioata silica maualuga-borate lauiloa, e tusa ma le 80% silicon dioxide ma le 13% boron oxide.E ese mai i le Schott's Borofloat33®, o loʻo i ai isi mea tioata o loʻo i ai i le maketi, e pei o Corning's Pyrex (7740), Eagle series, Duran®, AF32, ma isi.
Faʻavae i luga ole oxide uʻamea eseese,tioata silica maualuga-boratee mafai ona vaevaeina i ni vaega se lua: silica maualuga-borate o loʻo iai alkali (eg, Pyrex, Borofloat33®, Supremax®, Duran®) ma le alkali-free high-borate silica (e aofia ai Eagle series, AF32).E tusa ai ma faʻatusatusaga eseese o le faʻalauteleina o le vevela, e mafai ona faʻavasegaina tioata silica maualuga-borate alkali i ituaiga e tolu: 2.6, 3.3, ma le 4.0.Faatasi ai ma i latou, o le tioata faʻatasi ai ma le faʻalauteleina o le vevela o le 2.6 o loʻo i ai se faʻaitiitiga maualalo ma sili atu le faʻafefeteina o le vevela, e talafeagai ai e fai ma sui sui motioata borosilicate.I le isi itu, o le tioata faʻatasi ai ma le faʻalauteleina o le vevela o le 4.0 e masani ona faʻaaogaina mo faʻaoga faʻafefe afi ma e iai mea lelei e faʻafefe ai le afi pe a uma ona faʻamalosi.O le ituaiga e masani ona faʻaaogaina o le tasi e iai le faʻalauteleina o le vevela o le 3.3.

I se aotelega, pe a faatusatusa i le ipu malamalama soda lime,tioata boroslicatee sili atu le mautu vevela, mautu kemisi, felauaiga malamalama, ma meatotino eletise.O le iʻuga, o loʻo i ai tulaga lelei e pei o le tetee atu i vailaʻau faʻamaʻi, faʻateʻa vevela, faʻaogaina lelei faʻainisinia, maualuga le vevela, ma le maualuga o le maaa.O le mea lea, ua lauiloa foi otioata vevela, tioata fa'ate'ia fa'afefe vevela, tioata maualuga le vevela, ma e masani ona faʻaaogaina o se tioata faʻapitoa e faʻafefe afi.E faʻaaogaina lautele i alamanuia e pei o le malosi o le la, vailaʻau, vailaʻau faʻapipiʻi, optoelectronics, ma faatufugaga teuteu.
