Porous Fireproof Material Suitable for Glass Production, Method for the Production Thereof, and Uses

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel method for producing porous fireproof (refractory) materials specifically optimized for glass production. The key innovation is adjusting the pore volume of the refractory material to function as an 'oxygen sink,' achieved by introducing substances that create a reducing environment within the pores. This reduces the penetration of molten glass into the material, thereby minimizing corrosion, impurities, and other production disadvantages.

Use CasesContent extracted from patent full text and abstract with AI.

• Lining furnaces, tanks, or vessels in glass manufacturing plants to enhance their durability and lifetime.
• Reducing defects (like bubbles or inhomogeneities) in produced glass due to fewer impurities from refractory corrosion.
• Upgrading or retrofitting existing glass production facilities with improved porous fireproof lining.
• Other high-temperature glass processing operations that require refractory materials with high corrosion resistance.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly enhanced corrosion resistance for refractory materials exposed to molten glass, leading to longer service life.
• Reduction of glass contamination from dissolved refractory materials, improving the final product's quality.
• Lower occurrence of production issues such as bubbles and inhomogeneities in glass.
• Potential for simpler, less expensive refractory production processes compared to conventional surface coatings or exotic materials.
• Flexibility to adjust material properties by choosing different reducing agents (gases, liquids, or metals) based on application requirements.
