According to experiences and practice in the factory, a several approaches that make a reduction in glass prescription of Na2O-CaO-SiO2 system have been compared . The way which adapts to production are found for the factory.
Through analysing the design technology of the glass component, its optimum densigned method for using the computer was put forward ,and the implement and examples were provided The design concept can be used in other calculable products, which will bring great benefits in economy and society
The paper discusses the conditions to make glass-ceramics decorative plate using albite as major feedstock. Because the main ingredients of albites are SiO2 and Al2O3,we select CaO-Al2O3-SiO2 system as the glass formulation basis. It dissects the influence of nucleating temperature and crystallization temperature on the finished products and gets the glass-ceramics decorative plate whose main crystal phase is β-wollastonite.
Proper addition of the content of rare element Li 2O and substitution of less Na 2O with K 2O in the dispensation formula of DC glass should increase the body resistance of the product and avoid heat breakover phenomena from occurrence.
在玻璃配方中适当增加稀有元素Li2 O的含量 ,用K2 O取代少量Na2 O ,以提高产品的体电阻 ,避免热击穿现象的发生。
A weak concentration of non-magnetic impurities can give rise to a new state that we call "semi spin glass", in which a ferromagnetic component coexists with a transverse, spin glass component.
Depth-profiles using plasma-based SNMS with 410 eV argon ions were measured to check for migration processes within the glass component.
Textural features of the glass component can be very helpful for inferring aspects of eruptive dynamics.
Scanning electron microscopy of the glass component of tephra from single explosions show predominantly blocky and blocky/fluidal clast types, interpreted as being the product of vulcanian type explosions.
The next time you are dining, take a moment for a closer look at your food, and see if you can detect a feature comparable to that of a broken metal, plastic, or glass component.
Opal glass bottles made in tank furnace are used as substitutes for pottery bottles in order to improve the packaging of Maotai spirits. The compositions, melting process and properties of the opal glass together with its defects and cure measures are described.
The compositions, melting process and properties of chromium aventurine glasses are described; some manufacture problems are discussed.
Effect of heat treatment on the machnical strength of some glass-ceramics selected from Na2O-CaO-Al2O3-SiO2 system has been specially investigated by means of othorgonal testing method. A comprehensive analysis of the results together with those obtained by DTA, heatable stage microscope, X-ray diffraction and scanning electron microscope studies has provided the basis for the manufacture of Na2O-CaO-Al2O3-SiO2 system glass-ceramics of commercial value.
