掺杂p—TP和POPOP的内烁玻璃的研究

把有机冰烁激活剂p-TP和POPOP掺入低熔融温度的无机玻璃中，对闪烁玻璃的荧光光谱、玻璃的透光率和有机激活剂在玻璃中的实际含量进行了研究，结果表明，p-TP和POPOP可以掺入低熔融温度玻璃中并稳定存在，但是由于有机激活剂在引入过程中的挥发，它们在玻璃中的含量相对较低。由于玻璃基体中重原子的影响，闪烁玻璃的发射峰向长波方向移动，POPOP已起不到波长转换剂的作用，而是本身作为激活剂而发光。     

火山凝灰岩微晶玻璃的研究

以火山凝灰岩为主要原料研制成了以β－硅灰石为主晶相的微晶玻璃。高ＣａＯ含量玻璃核化、晶化后整体均匀结晶成为乳白色或浅黄色微晶化制品；低ＣａＯ含量玻璃烧结、晶化后成为花纹清晰的微晶玻璃大理石。高ＣａＯ含量玻璃由于ＣａＯ含量高，热处理时严重分相，分相有利于玻璃整体均匀析晶；低ＣａＯ含量玻璃在大量析晶之前基本烧结，由于表面效应在玻璃颗粒表面诱发β－硅灰石晶体，并由表及里长大为针状晶体。     

氟铝酸盐玻璃的研制

氟铝酸盐玻璃是一种新型的透红外氟化物玻璃。本文研究了RF_2-AlF_3-YF_3系统玻璃的形成能力,报导了玻璃的折射率、密度、特征温度和粘度等物理性质和化学组成的关系。并且在非等温条件下,用差热分析法研究了在熔体冷却和玻璃再加热过程中的晶化动力学;用x射线衍射方法确定了失透玻璃中的晶相。实验结果表明氟铝酸盐玻璃具有从紫外0.2μm到中红外7μm宽的透光范围,低的折射率、高的阿贝数和其它好的物理化学性质,与氟锆酸盐玻璃相比这种玻璃还有较好的化学稳定性和较高的机械强度。     

溶胶凝胶法对相玻璃转变行为的影响

本文分别采用溶胶凝胶法和常规法制备钠钙硅玻璃,液相温度和不混溶上限温度用光学显微镜和透射电镜进行测定。结果发现溶胶凝胶法(SGD)制备的玻璃液相温度比同组成的常规法(CD)制备的玻璃液相温度要高。对于组成落在介稳分相区的玻璃,溶胶凝胶法玻璃的不混溶上限温度要比相应的常规法玻璃高,而对于落在不稳分相区的玻璃则两种方法制备的玻璃具有相同的不混溶上限温度。该现象归迹于这两种不同方法制备的玻璃结构上稍有差别,即溶胶凝胶法制备的玻璃结构中含有较多的OH~-而导致的;这种结构上的差异引起了玻璃在析晶或分相期间的动力学和热力学上的不同。     

Preparation and Spectroscopic Properties of Ce-Doped High-Silica Glass

In order to develop a novel electric light source, the doped high-silica glass was studied on the preparation and spectroscopic properties . The porous glasses were made firstly and were then immersed in the solution containing Ce ion. Thereafter, the high-silica glasses containing Ce ion were prepared by sintering the porous preform. The spectroscopic properties were studied before and after heat-treatment in H2 . The experimental results indicate thai, the suitable temperature schedules are the most important to prepare doped high-silica glass. The study of the spectra shows that Ce ion can be reduced to low valence state when it is heat-treated in H2 . It can be used to adjust the UV aut-off wavelength of high-silica glass by changing the valence state of Ce ion.

Structure of Bi2O3-ZnO-B2O3 system low-melting sealing glass

Bi_2O_3-ZnO-B_2O_3 system glass is a kind of lead-free low melting sealing glasses. The structure of Bi_2O_3-ZnO-B_2O_3 system low-melting sealing glass was investigated by DSC, FT-IR, XRD and SEM. The results show that with the increase of B_2O_3 content, the transition temperature Tg and softening temperature T_f of Bi_2O_3-ZnO-B_2O_3 system low-melting sealing glasses increase, which leads to the liquid phase precipitation temperature increasing and promotes the structure stability in the glass. With increasing the heat treatment temperature, a large number of liquid phases appear in samples and the sinter efficiency of the samples increases. The FT-IR spectra of the glasses show the presence of some bands that are assigned to vibrations of Bi-O bond from [BO_3] pyramidal and [BiO_6] octahedral units and B-O from [BO_3] and [BO_4] units. With the decrease of B_2O_3 content, the crystallization tendency of the glass increases. In glass samples B_1 and B_2, crystallization starts at 460 ℃ and 540 ℃, respectively. Both of them precipitate Bi-(24)B_2O_(39) phases.     

Optimization of spectroscopic properties of ytterbium-doped laser glasses

Four laser glasses with high emission cross sections are experimentally obtained. The laser performance parameters are determined from the spectroscopic parameters of these glasses and compared with those of developing laser glasses abroad. It is shown that Yb~(3-)-doped telluorogermanate, Yb~(3 )-doped niobosilicate glasses have the highest emission cross section and gain coefficient, the smallest minimum pumping intensity and saturation pumping intensity, and the lowest minimum fraction of excited ions. Yb~(3 )-doped borate glass follows just behind them. These glasses have some spectroscopic advantages over laser glasses developed recently elsewhere. Yb~(3 )-doped phosphate glass is comparable to phosphate laser glass which had high emission cross section and was developed recently by HOYA Corporation in Japan.The domestic glasses with optimum spectroscopic properties may be promising candidates for applications in high-average power and high-peak power solid state lasers, especially laser for the ne     

Origin of Chinese ancient glasses——study on the earliest Chinese ancient glasses

The earliest Chinese ancient glasses before the West Han Dynasty (200 BC) from different regions are studied. The glass samples were unearthed from Hunan, Hubei, Yunnan, Sichuan, Guizhou, Guangdong and Xinjiang of China. The chemical composition of these glasses samples is analyzed by proton induced X-ray emission (PIXE) technique, energy dispersive X-ray fluorescence (EDXRF) method and inductively coupled plasma atomic emission spectrometry (ICP-AES). It is shown that the glass chemical compositions belong to barium-lead silicate BaO-PbO-SiO2, potash soda lime silicate K2O (Na2O)-CaO-SiO2 (K2O/Na2O>1), soda potash lime silicate Na2O (K2O)-CaO-SiO2 (K2O/Na2O＜1) and potash silicate K2O-SiO2 glass systems, respectively. The origins of the earliest Chinese ancient glasses are discussed from the archaeological and historical points of view. These four types of Chinese ancient glasses were all made in Chinese territory using local raw materials. The glass preparation technology was related to the Chinese ancient bronze metallurgy and proto-porcelain glaze technology. The glass technology relationship between the East and the West is analyzed at the same time.

Design and calculation of low infrared transmittance and low emissivity coatings for heat radiative applications

The infrared transmittance and emissivity of heat-insulating coatings pigmented with various structural particles were studied using Kubelka-Munk theory and Mie theory. The primary design purpose was to obtain the low transmittance and low emissivity coatings to reduce the heat transfer by thermal radiation for high-temperature applications. In the case of silica coating layers constituted with various structural titania particles (solid, hollow, and core-shell spherical), the dependence of transmittance and emissivity of the coating layer on the particle structure and the layer thickness was investigated and optimized. The results indicate that the coating pigmented with core-shell titania particles exhibits a lower infrared transmittance and a lower emissivity value than that with other structural particles and is suitable to radiative heat-insulating applications.
