摘要 翻译 谢谢好心人！

| 拓宽烧结温度范围的机理是添加的B2O3在熔体中可以形成具有三维空间连接作用的硼氧四面体[BO4]，减少熔体中非桥氧离子的数目，起着“补网”作用。硼的加入使熔体之网络结构紧密聚集，粘度提高，这时的熔体结构中除了原有的硅氧四面体网络和铝氧四面体网络外，还形成了硼氧四面体网络，硼硅氧四面体网络、硼铝氧四面体网络及其它的含硼四面体网络结构。所以红柱石基陶瓷中的熔体有较高的高温粘度，改善了瓷坯的抵抗高温变形的能力，而且当温高上升时，粘度的降低也是较为平缓的。所以红柱石基陶瓷烧结温度范围由20℃拓宽到40℃。 |

给译文之前有点小小疑问需要问一下作者，文中倒数第二句“所以红柱石基陶瓷中的熔体有较高的高温粘度……”是根据前面的这句话直接得出来的吗？如果是的话，那前面应该是逗号了，而且整个结合起来看的话，最后的一句来才是总结概括，前面都是陈述其原因的吧。 PS：以下译文就是按我上面的理解来处理的，供你参考。对了，专业词汇我不是很肯定，你重点看一下。 【译】The mechanism of broaden sintering temperature range is the added B2O3 in the melt can be shaped as boron-oxygen tetrahedron [BO4] with three-dimensional space connection function, which reduces the number of non-bridging oxygen ions in the melt, and plays the role of mending nets. With boron in, the network structure of the melt clustered tightly and the viscosity increased, here in addition to the original silicon-oxygen tetrahedral network and the aluminum-oxygen tetrahedron network in the melt structure, the boron-oxygen tetrahedron network, boron silicate Network, boron-aluminum-oxygen tetrahedron network and the other containing boron tetrahedral network structure were formed, so the melt in andalusite-based ceramic has higher temperature viscosity, which improved the ability to resist high temperature deformation of porcelain bodies. When the temperature rises, the viscosity reduction is fairly gentle. Therefore, andalusite-based ceramic sintering temperature range should be broaden from 20°C to 40°C. |
