Currently, the market demand for high-purity, durable and low-pollution industrial ceramic crucibles keeps rising. The 99.3% alumina ceramic crucible launched by Yunxing Industrial Ceramics has become the top choice for high-temperature industrial operations. Thanks to its ultra-high purity, excellent overall performance and strict quality control, it is widely recognized and favored by clients across the industry.
Leveraging the advantages of ultra-high purity alumina material, this crucible features excellent high-temperature resistance. Its melting point reaches 2050°C. It can operate stably for a long time at 1600°C and withstand temperatures between 1700°C and 1800°C for short periods, fully meeting the process requirements of most high-temperature calcination, melting, sintering and ash content testing.
Yunxing 99.3% alumina ceramic crucibles deliver exceptional chemical and thermal stability. Resistant to acid, alkali and molten medium corrosion, they can withstand erosion from most acidic and alkaline chemical reagents as well as high-temperature molten materials. The crucibles will not react with test samples or industrial raw materials, effectively ensuring material purity and accurate experimental data.
Meanwhile, their low coefficient of thermal expansion endows the products with outstanding thermal shock resistance. They can endure extreme temperature fluctuations from intense heat to sudden cooling, and are not prone to cracking or damage under rapid heating and cooling conditions. This makes them well-suited for continuous industrial operations and frequent laboratory experiments.
According to industry data, low and medium-grade alumina crucibles suffer from insufficient purity and poor stability, which often lead to sample contamination, failed experiments and a higher rate of defective products in production. By contrast, high-purity alumina crucibles with a purity of over 99% have become the mainstream choice for high-end industrial applications and scientific research.
Yunxing Industrial Ceramics accurately caters to market demands by abandoning extensive production methods. Adopting sophisticated slip casting and high-temperature sintering technologies, our 99.3% alumina ceramic crucibles feature three core strengths: high cleanliness, superior stability and excellent durability, outperforming conventional standard products across the industry.
With excellent product quality, Yunxing 99.3% alumina ceramic crucibles are widely used in metallurgy and mineral resources, chemical analysis, university research laboratories, new material sintering, electronic ceramics, special glass manufacturing and other fields, serving thousands of industrial enterprises and scientific research institutions.
