Abstract: Glass infiltrated metal oxide infrastructures are formed by providing a glass which is suitable for infiltration and compatible with the metal oxide infrastructure; heating the glass in a nitrogen rich environment; and infiltrating the metal oxide infrastructure with the glass. Stress corrosion in a glass infiltrated metal oxide infrastructure is avoided or reduced by heating a glass composition under a nitrogen gas atmosphere before infiltrating the metal oxide infrastructure.

Abstract: The invention relates to a method for manufacturing a composite of a porous metal oxide infrastructure and a glass infiltrated in the pores of the infrastructure, wherein the method comprises at least the following steps: providing a glass which is suitable for infiltration and compatible with the metal oxide infrastructure; heating the glass in a nitrogen rich environment; and infiltrating the metal oxide infrastructure with the glass. The invention also relates to a method for avoiding or reducing stress corrosion in a glass infiltrated metal oxide infrastructure, comprising heating a glass composition under a nitrogen gas atmosphere before infiltrating the metal oxide infrastructure. The invention further relates to a glass infiltrated metaloxide infrastructure obtainable by any of these methods.

Abstract: A method for coating yarn is proposed, including steps in which the yarn is first placed in contact with a dispersion of the coating agent in a dispersing agent or with the coating agent in melted form, optionally excess dispersion or melt is scraped back off the yarn, and then the coating is formed on the yarn, where in the case of the dispersion this occurs by means of at least partially removing the dispersing agent by heating, and the yarn thus coated is then cooled down and wound, which is distinguished by the fact that the coated yarn undergoes additional cooling before winding.
