1.离子交换法将稀释的水玻璃过滤除杂质后经阳离子交换，阴离子交换，调节ｐＨ值，经蒸发或超滤浓缩，制得硅溶胶。

2. 硅粉法将蒸馏水及氢氧化钠（试剂级）加到反应槽中，升温至65℃，加入一定量的氨水调整碱度，在搅拌下分批加入硅粉，控制温度在8.3℃以下，硅粉加完后继续搅拌2～3h，待ｐＨ值降至9～10时，取样分析，反应完成后在搅拌下冷却至50℃，经自然过滤，制得硅溶胶产品。未反应的硅粉可回收再用。 3.硫酸法将稀释的水玻璃与稀硫酸混合于20～30℃进行反应制得硅凝胶，老化4h，用2%～2.5%的稀硫酸浸泡1h，用40～50℃的水洗涤，在转筒烘干器中脱水至含水量≤80%，经烘干至水分含量≤10%，置于500～550℃活化炉中活化，经筛选制得粗孔微球硅胶。 4. 具体工艺流程为：

二氧化硅能吃吗？二氧化硅对人体有害吗？

2019-07-17 21:40:19

二氧化硅，化学术语，纯的二氧化硅无色，常温下为固体，化学式为SiO₂，不溶于水。不溶于酸，但溶于氢氟酸及热浓磷酸，能和熔融碱类起作用。自然界中存在有结晶二氧化硅和无定形二氧化硅两种。二氧化硅用途很广泛，主要用于制玻璃、水玻璃、陶器、搪瓷、耐火材料、气凝胶毡、硅铁、型砂、单质硅、水泥等，在古代，二氧...

二氧化硅密度是多少？二氧化硅的用途有哪些？

2019-07-17 21:41:46

二氧化硅又称硅石，化学式SiO₂，密度为2.2g/cm3。自然界中存在有结晶二氧化硅和无定形二氧化硅两种。结晶二氧化硅因晶体结构不同，分为石英、鳞石英和方石英三种。纯石英为无色晶体，大而透明棱柱状的石英叫水晶。若含有微量杂质的水晶带有不同颜色，有紫水晶、茶晶等。普通的砂是细小的石英晶体，有黄砂（较...
