CONDUCTIVE GLASS COMPOSITION AND GROUNDING PARTS OF MAGNETIC RECORDING MEDIUM FOR HARD DISK |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a conductive glass composition having <=100 MΩ.cm resistivity. SOLUTION: Tiss glass composition has the following composition as the main component and has <=100 MΩ.cm resistivity. The composition consists of 40 to 70 wt.% SiO2, 2.0 to 7.0 wt.% of Al2O3, 6.0 to 12.0 wt.% of Li2O and 23 to 35 wt.% of SnO2. The glass composition may contain 0.1 to 10.0 wt.% of Sb2O3 and 0.1 to 12.0 wt.% of B2O3.
