For mineralization stronger, join ferric oxide toward the complement in lime. CaO-FeO-SiO2 system has melting point to be the fusible fuse-element of 1105 Celsius, contain CaO 11. 5% , feO 45.5% and SiO2 43.0% , with CaO: FeO=l1: 3. The scale conform to of 965 closes. Mineralizer and fluid photograph composition still can be used make quartz extraction like the scales of a fish crystal computes even the requirement of crystal structure. The fluid photograph of in the future is comprised, by foregone constituent surface tension cent pressing value uses addition regulation to choose match. Because such computation obtains the content of small portion oxide, to large portion calculate again. To silica brick the department crystallizesFireproof material, the fundamental of a lot of phyletic production is doing academic research. Crystallization of another kind of blame fastens material, itsFireproof materialThe foundation is 2 oxidation silicon, make with vycor those who takeFireproof material. Because heat it to high temperature,the product that makes with vycor has; of good heatproof shake sex fast immerge arrives in cold water and not craze. Such goods is development direction. Wanted issue is to be able to be made take contain SiO2 to be more than the pure glass of 99% . Use slop normally pouring legal system makes vycor product, next firing perhaps do not burn. Still can make with vycor take fiber and product, the goods that dissolve body shapes directly, such. Vycor ingot itself is fireproof material uses the bath job layer that makes vitreous frit pit successfully. Quartz goods (pottery and porcelain) be in under 1200-1300 Celsius: Below temperature can use relatively for a long time, allow short inside 1600-1700 Celsius limits time to stay. Restricting the main reason that pottery and porcelain uses quartz is the Fang Shiying that happens below temperature of about 1200 Celsius crystallization is changed. Fang Shiying reduces the heatproof shake sex of goods apparently, the crystallization that has chemical inherent quality changes a course. To can form dinkum Fang Shiying crystal, make the oxygen that there should be sufficient amount when taking glass, produce crystallization to change then. When the chemical and metric formula of short of SiO2, do not produce crystallization to change. By this concept fused 2 oxidation silicon is chemical compound, if crystallization is done not have to change direction inside the condition, assure to maintain this to be not chemical and metric composition. The supplier of oxygen is foreign matter.
