Quartz glass is acidic material, except hydrofluoric acid and hot phosphoric acid showed any other inert, acid-resistant material is best. At room temperature, alkali and salt corrosion of quartz glass is minimal, and therefore does not preclude the use of quartz glass in these reagents. Quartz glass is a good acid material, in addition to more than 300 degrees of hydrofluoric acid and hot phosphoric acid at high temperatures, it is resistant *, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon and sulfur corrosion, its chemical stability acid-resistant ceramic equivalent of 30 times the equivalent of a nickel-chromium alloy and ceramics 150 times that of its high temperature, thermal shock, thermal expansion coefficient is very small. Transparent quartz glass than the opaque vitreous silica has better chemical stability, which is due to the presence of bubbles because the latter is exposed to the etching solution due to the increase in surface area. Caution: 1, quartz glass products is a valuable material, must be handled with care when using, be very careful; 2, various quartz glass has a maximum operating temperature, the use should not exceed this temperature, otherwise it will Crystallization or softening deformation; 3, quartz glass require high temperatures must be wiped clean before use. You can use 10% of hydrofluoric acid or lotion soak, then wash with high water or alcohol treatment. Operation should wear thin gloves, not allowed to touch the quartz glass with bare hands; 4, allowing for continuous use at high temperature quartz glass, quartz glass which is to extend the life and improve the heat resistance is good. Conversely, the high temperature intermittent use quartz glass, frequency of use is limited; 5, although quartz glass with high thermal stability, can withstand severe sudden changes in temperature difference. But the actual use, due to the different shape of the product residual strain and thermal stability have some differences, should be paid attention; 6, quartz glass-based acidic material, strictly avoid with alkaline material (such as water glass, asbestos use at high temperatures, potassium and sodium compounds, etc.) contact, otherwise it will greatly reduce the anti-crystallization properties.
