Posted: 11 August 2009 at 6:23am

Hi,
 
I would like to know if it is possible to use sols as binders in porous media (partially sintered ceramics) to increase their cohesion and mechanical properties.
 
I think it should be possible to partially fill pores/voids with a sol containing a high alkoxide/solvent ratio.I would like to use low (below 200°C) curing temperatures for my first experiments in order to keep an amorphous state and low density.
 
Does anyone here has an experience in such binding/impregnating applications? 
If yes, can you indicate me what kind of sol I should experiment?
 
Thanx

Hello,
 
I used another recipe, the name of the article is " optical high temperature sensor based on green up-conversion emission in Er3+ doped Al2O3" by B. Dong. I had the same problem as you and I heated up the solution. In this way I got the transparent solution.
 
Good luck

Hi everyone,

I would to ask if there anyone has compared TiO2 precursor, TTIP(titanium isopropoxide) and TBT (Titanium Butoxide)? The physical properties or optical properties?
Any information is highly appreciated.

Thanks,

Sol-Gel2009

August 2009,
PORTO DE GALINHAS
Brazil


The Organizing Committee is pleased to invite you to attend the XVth International Sol-Gel Conference that will be held from August 23 to 27, 2009 in PORTO DE GALINHAS, Pernambuco State, Brazil.

 

This biennial international conference focuses on both fundamentals and applications of sol-gel science. Previous conferences have taken place in Padova (Italy, 1981), Wuzburg (Germany, 1983), Montpellier (France, 1985), Kyoto (Japan, 1987), Rio de Janeiro (Brazil, 1989), Sevilla (Spain, 1991), Paris (France, 1993), Faro (Portugal, 1995), Sheffield (UK, 1997), Yokohama (Japan, 1999), Padova (Italy, 2001), Sydney (Austalia, 2003), Los Angeles (USA, 2005), Montpellier (France, 2007). The highly successful Sol-Gel Workshop series over 27 years ago attests that sol-gel science and technology is an extraordinarily and exciting multidisciplinary area of research.

 

You will find attached the first circular of the conference and you are invited to visit the conference website http://www2.fis.ua.pt/solgel2009/solgel2009.html for more related information. Abstracts are invited by 30 March 2009 for oral and poster presentations.

We look forward to welcoming you to PORTO DE GALINHAS in August 2009.

Hi,

You can use sodium meta silicate dissolved in water (pH >10) and gel it with HCl. But in this case the particle and pore sizes are too large (sometimes up to microns). If you clarify me the use of hydrogel for a specific application, I can suggest a better one.

All the best.

Hi, everybody,

I'm looking for gels which 
a) are hydrogels (i.e., have water as the liquid phase)
b) are stable against up to 10N alkali hydroxide solutions.

Does anybody know such gels and, possibly, how to
obtain them? (I'm a newcomer in the gel field ...).

Thanks in advance
