摘要:Hydrothermal synthesis of MCM-22(P) was carried out with two different silica sources, colloidal silica (28%) and silicic acid with different gel composition. The synthesis was carried out in stirring and static conditions with different crystallization time. MCM-22(P) modified...

摘要:... Here, the processes of colloidal silica transport and deposition were studied by displacing groundwater with recharge water. The results showed that significant amounts of colloidal silica transport occurred when native groundwater was displaced by HA solution. Solution co...

摘要:Colloidal silica and fumed silica are common slurry materials for oxide chemical mechanical polishing (CMP). Non-spherical colloidal silica particles are manufactured via a multi-step feeding method to compensate for the material removal rate of colloidal silica slurry, which ...

摘要:... Also, our experimental data shows that adding colloidal silica to PMMA and PI leads to a net decrease in the dielectric properties compared to the pure polymer.

摘要:... Colloidal silica (surface area 122.7 m²/g) and a ZSM-5 zeolite (surface area 261.3 m²/g) were used, in loadings from 2 to 10% weight. The results demonstrated that the addition of both materials was favorable to the TPS mechanical properties, however in higher loadings t...

摘要:Abstract(#br)Oxide CMP generally has used colloidal silica slurry and fumed silica slurry. To compensate the lower removal rate (RR) of colloidal silica slurry compared to the one of fumed silica slurry, the multi-step feeding method was used to produce a non-spherical silica par...
