The replacement of SF6 by refrigerant is under development. For example, R143a by AMC and FK by 3M Co. used as protection gas are both classified as HFC with short atmospheric lifetime and are easily to be decomposed into hydrofluoric acid, carbon monoxide and fluoric carbon monoxide at room temperature.
目前发展中的替代性保护气体以冷媒类为主，如澳洲AMC所采用的R134a及美国3M公司所开发的FK气体，两者都属於氟氢碳化合物，不过其半衰期短，即使在常温下，仍极易分解成氢氟酸、CO、COF2等，其中氢氟酸为有害物质，但因含量很少，且在高温下易与镁液反应，故对人体的为害很小。

However, the gelation tune was decreased with the increase of water amount and increased with the increase of ethanol amount.
在类似"两步法"中，通过同时使用的氢氟酸和氨水，凝胶化时间更短，其最佳条件是无水乙醇和水与正硅酸四乙酯的体积比各自是4和0.6，同时加入氢氟酸和氨水的体积比为1：1时，获得的比表面积最大。

When the temperature is above 100℃, no reaction of SiO_2 with gaseous hydrogen fluoride is observed, but the reaction is accelerated when the surface of SiO_2 is coated by a special polymer film.
二氧化硅与气相氟化氢的反应和与氢氟酸的反应不同，当温度高于100℃时，气相氟化氢与裸露的二氧化硅无明显反应，当二氧化硅表面涂上一层特殊聚合物膜时，反应可很快发生。
-
The sample was dissolved by hydrofluoric acid and hydrogen nitrate, then the tantalite and hydrofluoric acid formed TaF6- in the media of tartaric acid－hydrofluoric acid.
试样以氢氟酸、硝酸溶解后，在酒石酸－氢氟酸介质中，钽酸与氢氟酸形成阴离子TaF6-，与结晶紫生成蓝紫色的络合物，用苯萃取出来采用光度法测定钽量，测定结果均在国标允许误差范围内。
