Architectural Decorative Microcrystalline Glass Testing

Glass-ceramics for building decoration are polycrystalline solid materials produced by controlled glass crystallization processes. Their structure, composed of both crystalline and glass phases, gives them a dense texture and a jade-like luster. These materials are manufactured primarily using solid waste such as industrial slag and tailings as raw materials, through sintering or calendering processes. They exhibit excellent wear resistance, acid and alkali corrosion resistance, freeze-thaw resistance, and a low coefficient of thermal expansion, with water absorption close to zero and outstanding stain resistance.

The company has established the largest building ceramic testing center in Northwest China, covering an area of 3,000 m². It holds comprehensive qualifications for GB/T 4100-2015, ISO 13006, EN 14411, and other standards, issuing over 4,000 ceramic tile test reports annually. The National Center for Quality Inspection and Testing of Building and Sanitary Ceramics provides enterprises with customized testing services, one-stop inspection, certification, and technical guidance.
