As early as February 21, business micro news published "The Ministry of Commerce Held an Online Policy Briefing on Stabilizing Foreign Trade, stabilizing foreign investment and promoting consumption". At the briefing, Li xingqian, director of the foreign trade department of the Ministry of commerce, said in response to the reporter's question of whether the canton fair this spring will be postponed or cancelled, that at present, preparations for the 127th canton fair are proceeding in an orderly manner as planned.

Do nucleic acid on time, actively respond to home isolation, do not go out without contact, wear a mask when going out, and do a good job of disinfection and disinfection and sterilization when going home.

Jinzhou Yunxing Industrial Ceramics Co., Ltd. was established in May 2000. Its predecessor was Jinzhou Yunxing Technology Development Co., Ltd., which was located in the factory building of the High-tech Zone Enterprise Incubator on Yulu Street in the High-tech Zone. In April 2002, it moved to a leased factory of the Taihe District Agricultural, Industrial and Commercial Corporation.

With the rapid development of China's high-end manufacturing industry, the application scenarios of alumina ceramic crucibles continue to expand. They have extended from traditional metallurgy to high-end fields such as 12-inch semiconductor wafer manufacturing and sapphire crystal growth. Their standardized use is crucial to the safety and accuracy of experiments and production.

Recently, as a high-performance inorganic non-metallic material, alumina ceramic beads boast unique advantages and have been widely applied in multiple industrial fields including petrochemicals, new energy and environmental protection. They serve as a crucial supporting material driving industrial upgrading, and their excellent properties and diverse application scenarios have attracted extensive attention across the industry.

With outstanding properties such as high hardness, high temperature resistance, corrosion resistance and excellent electrical insulation, alumina ceramics are known as "high-performance core materials" in the advanced manufacturing sector. As a critical process that determines product performance and cost, its sintering technology has long attracted extensive attention across the industry.

Alumina ceramic is a polycrystalline inorganic material composed of multiphase structures including grains, grain boundaries, pores, and impurities, which constitutes the essential root cause of its opacity.

Alumina ceramic is an advanced ceramic material sintered at high temperature with high-purity α-Al₂O₃ as the main raw material. It features a unique combination of properties, perfectly meeting the requirements of extreme working conditions and precision applications.

Visual inspection serves as the most convenient primary screening method, allowing quick detection of obvious defects without the need for professional tools. High-quality alumina ceramic sheets feature a flat, smooth surface with a fine, burr-free touch and a jade-like gentle luster. They are free from defects such as scratches, cracks, air pores, black spots, and edge chipping, with a uniform and consistent color.

Corundum castable and corundum-mullite castable are both high-end monolithic refractory materials. Relying on their unique compositional advantages, they play an irreplaceable role in high-temperature environments.
