Abstract: A glass material with a low dielectric constant and a low fiberizing temperature includes silicon dioxide, boron trioxide, aluminum oxide, calcium oxide, phosphorus pentoxide and zinc oxide. The silicon dioxide makes up 45%-52% by weight of the glass material. The boron trioxide makes up 25%-30% by weight of the glass material. The aluminum oxide makes up 10%-14% by weight of the glass material. The calcium oxide makes up 1%-4% by weight of the glass material. The phosphorus pentoxide makes up 0-3% by weight of the glass material. The zinc oxide makes up 1%-5% by weight of the glass material. The reduced silicon dioxide content and calcium oxide content and addition of phosphorus pentoxide and zinc oxide in the glass material lower the dielectric constant and fiberizing temperature of the glass material.

Abstract: A glass composition and a glass fiber made thereof have a low thermal expansion coefficient and include a main material, a fluxing material and a reinforcing material. The main material includes silicon dioxide having a percentage by weight of 55%-66% of the glass composition. The reinforcing material includes aluminum oxide having a percentage by weight of 10%-20% of the glass composition. The fluxing material includes magnesium oxide, zinc oxide, and titanium dioxide. The percentage by weight of magnesium oxide is 3%-12% of the glass composition, the percentage by weight of zinc oxide is 0.01%-7% of the glass composition, and the percentage by weight of titanium dioxide is 0.01%-6% of the glass composition. By adding zinc oxide and titanium dioxide, the thermal expansion coefficient of the glass composition can be lowered.

Abstract: A glass material with a low dielectric constant attributable to a high weight percentage of boron trioxide includes at least one component for forming the main constructure of the glass material, a fluxing component, a reinforcing component, and a modifier; wherein the at least one component for forming the main constructure of the glass material includes silicon dioxide (SiO2); the fluxing component includes boron trioxide (B2O3); the reinforcing component includes aluminum oxide (Al2O3); and the modifier includes calcium oxide (CaO). The glass material is characterized in that it has a boron trioxide (B2O3) content by weight of 30%-40%, which is higher than those in the prior art; a calcium oxide (CaO) content by weight of 1%-6%, which is lower than those in the prior art; and consequently a lower dielectric constant and a lower dissipation factor of the glass material than those in the prior art can be obtained.

Abstract: A glass material with low viscosity and a low bubble content attributable to a low weight percentage of silicon dioxide includes boron trioxide (B2O3), magnesium oxide (MgO), aluminum oxide (Al2O3), and calcium oxide (CaO) in addition to silicon dioxide (SiO2); wherein Silicon dioxide (SiO2) constitutes 45%-51% by weight of the glass material, boron trioxide (B2O3) 25%-35%, magnesium oxide (MgO) 0.01%-2%, aluminum oxide (Al2O3) 10%-14.5%, and calcium oxide (CaO) 4%-10%. As the silicon dioxide (SiO2) content is lower than in the prior art, the glass material has lower viscosity, and hence a lower bubble content, than in the prior art, and this allows products made of the glass material to have a higher yield than products made of the conventional glass.
