Ceramic wares; for laboratory, chemical or other technical uses, articles having a hardness equivalent to 9 or more on the Mohs scale

HS code 690912 covers a specialized category of ceramic products designed for laboratory, chemical, and other technical applications. These high-performance ceramic wares are characterized by their exceptional hardness, equivalent to 9 or more on the Mohs scale. This industry plays a crucial role in supporting various scientific, industrial, and technological sectors by providing durable, heat-resistant, and chemically inert materials essential for a wide range of specialized equipment and processes.

The production of HS 690912 ceramic wares typically involves a multi-step process. First, high-purity raw materials, such as alumina, silica, and other specialized ceramic compounds, are carefully selected and mixed. The mixture is then subjected to high-temperature firing, often in excess of 1,500°C, to achieve the desired level of hardness and chemical resistance. Advanced manufacturing techniques, such as precision molding and advanced sintering methods, are employed to ensure the consistent quality and performance of the final products.

The main inputs required for the production of HS 690912 ceramic wares include high-purity raw materials, such as 2818 Aluminium oxide, 2506 Quartz, and other specialized ceramic compounds. Specialized manufacturing equipment, such as high-temperature kilns and precision molding machines, are also essential for the production process. Additionally, skilled labor with expertise in ceramic engineering and materials science is crucial for maintaining the quality and consistency of these technical ceramic products.

HS 690912 ceramic wares are primarily used in a variety of laboratory, chemical, and other technical applications that require exceptional hardness, thermal stability, and chemical resistance. These products are often used in the manufacture of 9027 Instruments and apparatus for physical or chemical analysis, 8419 Machinery, plant or laboratory equipment, and other specialized equipment used in scientific research, industrial processes, and advanced technologies. The outputs of this industry are essential for supporting the development and advancement of various sectors, including healthcare, energy, and materials science.
