Folasaga ole Quartz Fiber:
Tensile malosi 7GPa, tensile modulus 70GPa, o le SiO2 mama o quartz fiber e sili atu i le 99.95%, ma le mamafa o le 2.2g / cm3.
E fetu'una'i mea alava inorganic ma maualalo dielectric tumau ma le maualuga vevela tetee. O loʻo i ai tulaga faʻapitoa faʻapitoa i le fanua o le vevela ultra-maualuga ma le aerospace, o se sui lelei mo le E-tioata, silica maualuga, ma filo basalt, o se vaega e suitulaga i le aramid ma le carbon fiber. E le gata i lea, o lona faʻalauteleina o laina laina e laʻititi, ma faʻateleina modulus elastic pe a faʻateleina le vevela, lea e matua seasea lava.

Pfaatinoga:
1. Dielectric meatotino: maualalo dielectric faifai pea
O le alava Quartz e sili ona lelei le dielectric, ae maise mea faʻamautu dielectric i ala maualuga ma maualuga vevela. O le gau o le quartz fiber e na'o le 1/8 o le D-glass I le 1MHz. A maualalo ifo le vevela nai lo le 700 ℃, o le dielectric faifai pea ma dielectric gau o le quartz fiber e le suia i le vevela.
2.Tete'e o le vevela tele-maualuga, umi le ola i le vevela o le 1050 ℃ - 1200 ℃, faʻamaluluina le vevela 1700 ℃, teteʻe o le vevela, umi le tautua
3. Low conductivity vevela, itiiti faʻalauteleina faʻamafanafana faʻatasi na o 0.54X10-6/K, o le tasi vaesefulu o alava tioata masani, e le gata i le vevela ma le vevela
4. Malosi maualuga, leai ni micro-cracks i luga o le fogaeleele, o le malosi faʻamalosi e oʻo atu i le 6000Mpa, lea e 5 taimi o le fiber silica maualuga, 76.47% maualuga atu nai lo le E-glass fiber
5. Lelei le faʻaogaina o le eletise eletise, resistivity 1X1018Ω·cm~1X106Ω·cm i le vevela 20 ℃ ~ 1000 ℃. O se mea fa'apipi'i eletise lelei
6. Mea tau kemikolo mautu, acidic, alkaline, maualuga vevela, malulu, fa'alauteleina le tumau malosi. Tete'e a'a
