Can the melting point be higher than the boiling point? -I'm suspecting the author has written the melting point as boiling point and vise versa. Therefore I'm going to do an experiment in a couple of days to see if it melts at 102^oC -Got a hold of silica gel, it did not melt at over 102^oC

Is silica gel pure silica? --207.81.94.148 03:08, 31 October 2007 (UTC)[reply]

Vandalism ?

Is the following sentence nonsense or am I missing something? Rsduhamel 08:31, 19 Dec 2004 (UTC)

Sodium silicate commands a 50 to 100 percent price premium over sodium hydroxide, and processors need the equivalent to 0.5 to 1 percent of it to the volume of crude oil as a neutralizing agent, depending on the acidity of the vegetable oil.

Found the original source of the sentence and fixed the article Rsduhamel 19:16, 19 Dec 2004 (UTC)

==Update==--PaladinZ06 22:05, 24 March 2006 (UTC) I've added some information, and changed the content of the timber treatment section. The use of sodium silicate as a wood preservative may not be common, but it was hardly dreamed up in 2005. I am in the process of using an old method at home that uses sodium silicate solution as a wood sealer/fireproofing which is then sprayed with a boric acid solution which keeps the bugs at bay and forces the sodium silicate to gel.[reply]

There are several common trade products available containing primarily sodium silicate for treating concrete and other masonry products.

I apologize for any errors I've introduced. I am a total newcomer to this. --PaladinZ06 22:05, 24 March 2006 (UTC)[reply]

Dishwashing Detergent

I've noticed that my dishwasher detergent containts sodium silicate. This should probably be worked into the article.

Sodium metasilicate is also used as a replacement for trisodium phosphate in painting preparation/degreasing. It works well in dishwashing except for the attack of glass. Softer, soda-lime glass is attacked via common ion solution effect, leaving the glass cloudy. As such, automatic dishwashing detergents containing appreciable amounts of sodium metasilicate should only be used for non-glass items like metal and plastics. Glazed stoneware is also susceptible to attack.

Silica Xerogel

According to the Nasa Space Sciences Questions and Answers FAQ (http://science.nasa.gov/faq/#anchor136932), sodium silicate gel, when air dried, forms silica xerogel, which is a similar to aerogel. Perhaps this wiki should be updated in regard to this?

Antifreeze (Bad!)

A friend of mine tried to use sodium silicate as an antifreeze in his car (prehaps misunderstanding its use as a cheap stop-leak compound). The stuff solidified while in his radiatior, requiring a complete cooling system replacement. Got2code 19:05, 14 June 2007 (UTC)[reply]
