| SO4 | ≤0.3% | |
| Cl | ≤0.15% | |
| Fe | ≤0.06% | |
| Water insoluble | ≤0.3% |
APPLICATION
With high-content of boron, this product is a great material of optical glass,
apparatus glass, hard borosilicate glass, electrovacuum glass and other special
glass. Our product reduce glass coefficient of expansion, improve heat and chemical
stability, increase irefractive index, better its lustre.
