二氧化硅玻璃

Scanning electron microcopy and laser light scattering spectroscopy show that the synthesized silicate particles are in perfect spherical shape and are monodispersed in sizes with their diameters of about 0.7 μm.

扫描电子显微镜和激光粒度仪分析表明，所合成的产物为大小约0.7 μm的二氧化硅球状颗粒，它们能够在玻璃衬底上自动排列成光子晶体。

It was found that the thickness of the film can improved with adding some mucilage glue.

增粘剂的加入可提高一次涂膜的厚度，低温烧结可在金电极上得到表面光亮的二氧化硅玻璃薄膜，绝缘性能良好。

Then again , although made of the same silica material as glass , opal is quiet different and that difference is what makes this precious stone so wonderful .

再说，虽然取得了相同的二氧化硅材料为玻璃，蛋白石是安静的不同，以及不同的是，是什么使这一珍贵的石头，所以美好。

A: Quartz is almost pure SiO2, while pyrex is SiO2 with trace amounts of other elements.

石英玻璃的成分几乎是纯二氧化硅（ SiO2），而派热克斯玻璃是二氧化硅与其它微量元素（ Ca， K， B 等）。

Quartz glass is special industrial technology glass made by silicon dioxide and is one kind of excellent basal material.

石英玻璃是用二氧化硅制造的特种工业技术玻璃，是一种非常优良的基础材料。

As the principal component in glass, silicon dioxide was used as early as 5000 BC.

作为玻璃的主要成分，二氧化硅早在公元前5000年就被使用。

The reflective coating was prepared with glass bubbles and Al 〓 coated glass bubbles used as pigments. The naked glass bubble went together during the coating drying because its'low density. When the Al 〓 coated glass bubbles used as pigments, the bubbles can be dispersed very well in the dry coating.

空心玻璃微球和氢氧化铝涂层玻璃微球作为填料时，涂料在400nm-2500nm范围内都具有较大反射率；纳米二氧化钛作填料时，在可见光区域具有较大反射，红外区域反射率较小；以纳米二氧化硅作为填料的涂料在整个紫外-可见-近红外区域反射率都很低。

The utilization proportions are more than 70%. But the composition of gangues is complex and their melting point is high, so that they must be added additives to reduce their melting point.

论文中采用的福建沙县田口钾长石尾矿和北京平谷金矿尾矿两种尾矿中二氧化硅(SiO_2)含量高，可以用于制备玻璃，为制备泡沫玻璃提供主要原料，尾矿的利用率达到70％以上。

What is disclosed includes OD-doped synthetic silica glass capable of being used in optical elements for use in lithography below about 300 nm.

本发明揭示了OD-掺杂的合成二氧化硅玻璃，它能够用于在约低于300纳米下进行光刻的光学元件中。

Liquid glass is composed of almost pure silicon dioxide, the chemical constituent of quartz or silica, basically like ordinary glass.

液态玻璃几乎是由纯二氧化硅构成的，二氧化硅就是石英或硅石中的化学成分，基本上象普通玻璃一样。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
