Low temperature co-fired ceramic (LTCC) has become the mainstream method for the high-density integration of electronic components. In order to meet the requirements of miniaturization and high-performance system applications, as the substrate support material, LTCC green tapes must ensure high quality and consistency. Additionally, in order to maintain accurate alignment of different layers, it is necessary to strictly control the shrinkage behavior of the green tape during sintering. The main factors affecting the shrinkage rate of LTCC green tapes from both material and process perspectives were summarized, including the particle size and morphology of inorganic powder, softening point of glass, the proportion of binder and plasticizers, casting speed, pressure of heat pressed laminations, and sintering curve. The sintering process and the reasons for shrinkage of green tapes were analyzed, and the impact of each factors and control methods on the quality of green tapes were discussed，providing reference for the preparation of high-quality green tapes.

X-ray fluorescence spectrometry (XRFS) was applied to determine the concentration of seven elements (Si, Fe, Al, Ca, Mg, K and S) in the desulfurization waste ash from float glass furnace. To eliminate matrix interference, calibration samples with different mass fractions were prepared by compounding certified reference gypsum material with calcium hydroxide and calcium carbonate to simulate the composition of desulfurization ash. These samples were prepared using the fusion bead method. The standard curves for each element determined by X-ray fluorescence spectrometry (XRFS) were corrected using the Fundamental Parameters (FP) method. The accuracy of this method was verified using gypsum standards, with the highest absolute error between the test results and the certified values being 0.34%. The results indicated that this method exhibited excellent stability and was suitable for routine monitoring of waste ash in float glass factories as well as for subsequent solid waste utilization testing.

Lanthanum crown glass has attracted much attention in the application field of car glass because of its excellent mechanical properties. A three-point bending strength tester was used to test and comparatively analyze the bending strength of the car glass samples before and after polishing, aiming to investigate the impact of surface roughness on its three-point bending strength. The results showed that the average bending strength of samples post surface polishing treatment increased by 9.4 MPa compared to the untreated samples, and the results exhibited great stability. Furthermore, by using numerical analysis methods to compare the mean values derived from the raw data, 90% confidence interval and 80% confidence interval, it is found that the 80% confidence interval can effectively remove outliers and accurately reflect the bending strength values of the samples.

In the field of pharmaceutical and food packaging, glass materials must have excellent water resistance to ensure that they do not endanger human health and safety due to increased alkali metal leaching from the inner wall. Using the glass formula design and adjustment system（GFDA-SYSTEM) fitting algorithm, this study investigated the influence of alkali metal oxides, alkaline earth metal oxides, and high-valence metal oxides on the leaching of Na2O from glass across various formulation adjustment ways, providing quantitative evidence for formulation design. Moreover, in the practice of adjusting formulations, attention was paid to the associated problems caused by the water resistance debugging technology. A holistic concept of prevention and control closed-loop systematization and formulation debugging systematization was established, providing practical guidance for debugging formulations and optimizing the water resistance and continuous stability of glass.

The new double-channel regenerator end flame glass furnace effectively addressed the energy-saving and production expansion challenges faced by glass factories in the narrow factory areas. The chimney was placed on the top of the second regenerator chamber, and the lower part of the chimney was designed into a venturi tube shape, with an ejector air tube installed inside. The high-speed airflow from the ejector fan created a suction force root of the chimney through the venturi tube, carring the wrapped flue gas out of the chimney. This design provided a solution for energy-saving transformation and production expansion of many glass factories with limited plant areas.

Ultra-thin electronic glass was widely used in applications such as display, touch screens and solar cells, where its coefficient of thermal expansion (CTE) significantly influences the thinness and reliability of devices. This paper explored the application of CTE in ultra-thin electronic glass and optimized the design, manufacturing and application of ultra-thin electronic devices by deep understanding of the thermal expansion coefficient.

To address the low efficiency of manual labeling in deep processing of glass bottles, an automatic labeling equipment based on four degrees of freedom (4-DOF) manipulator and servo turntable was developed. The contour features of the glass bottle equipped with machine vision recognition were used for positioning and labeling, and then the pressure labeling was carried out in turn. The prototype test showed that the average qualified rate of products after labeling and baking was about 98.12%, and the average time consumption of the whole labeling process was about 1.69 s per bottle, which showed that this technology realized flexible labeling efficiently and accurately, and it had significantly enhanced production efficiency and product quality.

Ultra-thin alkali aluminosilicate glass produced by the float process was taken as the research object. Considering that the warping after chemical tempering might be caused by the fact that the surface compressive stress (FCS) multiply by depth of stress layer (dDoL) of the atmosphere surface was larger than that of the tin surface, a method of coating on the air surface of the glass was adopted to reduce the ion exchange degree of the atmosphere surface during chemical strengthening and narrow the difference of FCS×dDoL on both sides of the glass. By exploring the effect of different coating solutions on toughened warping, it was found that the tetraethyl orthosilicate (TEOS) coating system had a significant effect. The glass samples of 26.4 cm×19.8 cm×0.7 mm were chemical strengthened at 400 ℃ for 4 hours, and the average warpage value was reduced by 27%. The apparent quality of the coated glass met the subsequent requirements, providing an effective way to reduce the toughened warping problem in ultra-thin glass production.

Cat scratch marks significantly impact the appearance quality and product yield of glass products, which is a defect of glass inhomogeneity. This paper discussed the causes and improvement measures of cat scratch marks defects caused by Al2O3-rich and ZrO2-rich compositions. It also introduced the concept of systematic process control, which encompassed multi-dimensional control from raw materials, batch preparation, melting, molding feed temperature system and stirring, so as to eliminate cat scratch marks defects.
