Artificial corundum

CPC v2.1 Code: 3796

About artificial corundum

cpc code 3796 covers the production of artificial corundum, a synthetic form of the mineral corundum. Artificial corundum is an important industrial material with a wide range of applications, from abrasives and cutting tools to specialized electronics and jewelry. As a highly durable and heat-resistant substance, artificial corundum plays a crucial role in various manufacturing and processing industries, contributing to the broader economy through its versatility and performance characteristics.

Production process

The production of artificial corundum typically involves the fusion of aluminum oxide (Al2O3) at high temperatures, often exceeding 2,000°C. This process, known as the Verneuil process, involves the controlled melting and crystallization of the raw materials to create synthetic corundum. The molten material is then carefully cooled and shaped into the desired forms, such as abrasive grains or specialized components.

Production inputs

The primary input for the production of artificial corundum is aluminum oxide, which is the main raw material. Additionally, the process may require specialized equipment, such as high-temperature furnaces, crucibles, and molds, as well as various auxiliary materials like fluxes and additives to control the crystallization and properties of the final product.

Production outputs

The primary output of the artificial corundum industry is the synthetic corundum itself, which is then used in a variety of applications. These include 3542 Abrasive products, 3544 Cutting tools and machine tool accessories, 3545 Special industry machinery, and 3679 Electronic components, n.e.c.. The versatility of artificial corundum allows it to be a key input for many downstream industries, contributing to the overall productivity and efficiency of the manufacturing sector.
