<p>Binder, filler, and refractory compositions and methods of using and making these compositions are disclosed. The binder composition comprises colloidal silica, a liquid material containing Si-OH groups, a solvent which is capable of solubilizing the liquid material and the colloidal silica, and at least one aprotic, non-ionic, non-metallic, organic compound which contains at least one element selected from P, S, B and N and which stabilizes the binder composition against self-gelling. The colloidal silica and the liquid material are present in a ratio by weight of from about 1:12 to about 75:1 respectively. The liquid material has at least about 20% by weight SiO2. The colloidal silica contains at least about 15% by weight SiO2. The solvent and the organic compound are present in amounts so as to solubilize the liquid material and the colloidal silica, to provide a binder composition which is stable against self-gellation, and to provide a binder composition which gels to a single phase.</p> |
