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.
