一种低介电常数玻璃粉及其制备方法
Abstract:
本发明公开一种低介电常数玻璃粉，按重量百分比包括：62～72%的SiO2、0.1～10%的Al2O3、23～32%的B2O3、0～1%的Li2O、0～0.5%的Na2O、0～1.5%的K2O、0～2%的CaO、0～2%的MgO、0～2%的BaO、0～2%的TiO2、0.5～3%的CaF2以及0.1～4%的NaCl或SnO；其中Li2O、Na2O与K2O合计重量百分比0～3%，CaO、MgO与BaO合计重量百分比0～3%；通过配料、熔制、水淬以及球磨的方法即可制得本发明玻璃粉；本发明玻璃粉具有介电常数低、介电损耗小、热稳定性高等特点，满足电子工业使用要求，且制备方法简单、成本低，适合大规模工业化生产。
Abstract(English):

The invention discloses low dielectric constant glass powder which comprises, by weight, 62-72% of SiO2, 0.1-10% of Al2O3, 23-32% of B2O3, 0-1% of Li2O, 0-0.5% of Na2O, 0-1.5% of K2O, 0-2% of CaO, 0-2% of MgO, 0-2% of BaO, 0-2% of TiO2, 0.5-3% of CaF2 and 0.1-4% of NaCl or SnO; wherein the total weight percentage of the Li2O, the Na2O and the K2O is 0-3%, and the total weight percentage of the CaO, the MgO and the BaO is 0-3%. The glass powder can be prepared by dosing, melting, water quenching and ball milling. The glass powder has the advantages of low dielectric constant, small dielectric loss and high thermal stability, and meets the requirements for electronic industry use. The preparation method is simple, low in cost and suitable for large-scale industrial production.
