稻壳灰表征及其石英循环再生的Substitute for the Production of Ceramic Gla代替釉陶瓷生产 I. Introduction 导言 II. 二。 Experimental Procedure 实验方法 III. 三。 Results 结果 IV. 四。 Conclusions 结论 Acknowledgments 致谢 References 参考文献 In this work a complete characterization of rice husk ash (RHA) was conducted in order to evaluate mainly the composition and the thermal reactivity in terms of crystalline phase evolution. 在这项工作中一个壳灰）完整的特征稻壳灰（以进行评估，主要的组成和演化的热结晶相反应性条款。 Moreover, the screening results of the research conducted on the possibility to use RHA as silica precursor in ceramic materials, such as ceramic glazes, were reported. 此外，在釉料甄别结果的可能性进行了研究陶瓷用壳灰为硅为前驱体陶瓷等材料，报告。 The selected frits were prepared in a semiindustrial furnace and the obtained glasses were investigated in comparison with the frits prepared from pure quartz. 选定的熔块编写了一semiindustrial炉和调查获得的纯石英玻璃是在准备从熔块比较的。 Besides, laboratory glazes were obtained and characterized following the technical rules. 此外，实验室釉和特点，得到以下的技术性法规。 This work allows to confirm the possibility to use RHA as silica precursor for the development of glazes for ceramic tile. 这项工作可以确认的可能性，使用易制毒化学瓦壳灰为硅陶瓷釉料的发展。 The results evidenced, however, that it is not possible for a generalized production substitution of quartz with RHA. 结果证明，但是，它不是生产替代壳灰可能具有广义的石英。 Abstract 摘要 I. Introduction 导言 II. 二。 Experimental Procedure 实验方法 III. 三。 Results 结果 IV. 四。 Conclusions 结论 Acknowledgments 致谢 References 参考文献 R ice husk ash (RHA) is obtained by burning the rice husk, and in particular it is produced in plants where rice milling is performed with cogeneration or similar facilities or in plants for the production of parboiled rice. 王仕稻壳灰 （壳灰）获得通过燃烧稻壳，尤其是水稻生产的蒸谷米在工厂里，大米或铣削演出，热电联产或类似设施，植物的生产。 In general, the so obtained RHA is dumped as a waste.一般而言，这样得到的壳灰是作为废物倾倒。 Globally, approximately 600 million tons of rice paddy is produced yearly worldwide.全球范围内，大约600万吨水稻生产每年全世界。 Assuming a husk to paddy ratio of 20%, 1 and an ash to husk ratio of 18%, 2 the total global ash production cou
