The results showed that functional nanometer ITO powders of 30-50nm size with dispersion performance can be prepared. The condition is that indium salt concentration is 88mmol/L, SnO2/In2O3 =5.3wt%, reaction solution PH value is 8, The precursor are thermally reduced at 450 ℃ under hydrogen gas ,at the sametime adding 6at.% KC1 salt to indium tin salts. Thus, satisfactory and stable dispersion of ITO particles in aqueous solution is obtained only through simple mechanical force.

KCl、反应铟盐浓度88mmol/L，掺杂比SnO_2/In_2O_3≈5.3wt%，维持PH值为8的反应条件下制备前驱体，前驱粉体在450℃，氢气气氛煅烧的条件下可生成功能性的具有很好分散性能的ITO粉末，粒径大小为30—50nm，此制备得到的粉体通过简单的机械分散可直接稳定的分散于水、醇介质，若通过分散剂处理后的分散体系可以稳定存在两个月以上。

The emulsion quartz stone material protective agent's solute has certain active multi-compositions and so on of functionality siloxanes and fluorine silicon hydride, this kind groups with the active ingredient carry alcoholysis reaction the ion condition water on quartz stone material surface, thus causes the siloxanes and the fluorine siloxanes has chemistry keying connection with the quartz stone surface, from outside to inside of the quartz stone surface and stone inside pore surface forms a kind of complex network structure, this kind of network structure is extremely dense, it may filter polar and carbon dioxide, slows down the speed that water molecules go in and out the quartz stone pore, so the quartz stone will not be soaked by the water molecules, meanwhile to be a barrier to stop alkaline compounds and salt to infiltrate from an interface to another, also can have the very good physical enhancement effect.

乳液型石材防护剂的溶质是具有一定活性的多官能度的硅氧烷和氟硅烷等组成，这种带有活性成份的基团与石材表层离子态水进行醇解反应，从而使硅氧烷和氟硅氧烷与石材表面进行化学键连接，由外向内在石材表面和石材内部毛的表层形成一种结构复杂的网状结构，此种网状结构极其密实，它可将极性水分子和二氧化碳进行过滤，减缓水分子进出石材毛孔的速度，不会被水分子浸湿，同时还有阻隔石材不同界面的碱性化合物和盐份向另外一个界面渗透，同时还能起到很好的物理增强效果。
