Chemical properties of quartz sight glass Ⅱ
Quartz sight glass is a good acid resistant material, but also resistant to neutral corrosion and reacts with alkali, but it reflects less speed. The chemical property of quartz sight glass is stronger than any engineering material. The chemical properties of the quartz sight glass at high temperature are incomparable to other materials. But quartz sight glass is not resistant and can decompose quartz sight glass. The reaction is as follows: SiO2+6HF - H2SiF6 - 2HF+SiF4. In 40% deep liquid, the surface erosion speed of quartz sight glass is 11.6 mg / M 2O hours, which is equivalent to 5.9 x 10-5cm/ hours. At 100, the erosion rate of 48% concentration to stone sight glass is 300-700 mg / h, and people use this characteristic to clean the quartz sight glass table. Face, to reach the product. The purity of the raw material is also used to clean the crystal surface, and quartz sight glass and heat are also chemically reflected. At 300 hours, 15 hours, the erosion volume is 58 grams / meter, 2500 hour temperature 15 hours, the erosion volume is 79 grams / meter, 2700 degrees when the temperature reaches 2700 grams / meter 2. No oxidized metal can react with silica sight glass, so it can melt platinum and platinum in quartz sight glass container. Alkali and alkaline earth compounds can accelerate quartz sight glass quartzification at high temperature, so do not use it, because there are Na ions in sweat, otherwise the alkali will be produced at high temperature. Some elements and oxides reacted with quartz sight glass at high temperature. Al (Al) reacted above 700 C, carbon (C) reacted above 1500 C, calcium (Ca) reacted above 600 C, lithium (Li) reacted above 250 C, (Hg) reaction at 700-800 C, reaction of phosphorus (P), Al2O3 reaction above 1200 C, BaO, CaO, CuO, Fe2O3, MgO at 950 degrees C and alkaline oxidation At more than 800 degrees centigrade, the substance accelerated crystallization, H2O was decomposed under high pressure above 500 centigrade (over 400 BA), and BaSO4 was reacted at 700 C. 10% concentrations were soaked at NaOH and KOH20 for 100 hours. The amount of corrosion was 0.095 mg /cm2, KOH was 0.019 mg /cm2; NaOH at 100, 5%, and 5% mg / cm2 for 10 hours.
