The chemical indicators of high purity fused quartz are as follows:
Impurity Elements | Al | Already | K | Ca | Fe | Of | Mg | Mn | Li | In | Cu | Cr | Co |
Content (ppm) | 16 | 1.2 | 0.3 | 0.6 | 0.5 | 1.0 | 0.07 | 0.1 | 0.9 | 0.06 | 0.06 | 0.01 | 0.05 |
High purity fused quartz mainly high purity quartz crucible, optical coating, low hydroxyl quartz
Glass tube (hydroxyl 6-10ppm before dehydroxylation, hydroxyl 1-1.2ppm after dehydroxylation), etc. Product specifications: 10-20 mesh, 30-50 mesh, 50-100 mesh, 100-200 mesh, 325 mesh, 1000 mesh, 5 micron, 2 micron, etc. Other specifications can be customized
