In the vast landscape of modern industry, tungsten powder, though seemingly unremarkable, plays a critical role as an unsung hero. From everyday electronics to soaring aerospace vehicles and high-performance automobiles, tungsten powder is indispensable.

Single crystal growth is a key process for the preparation of high-purity and structurally perfect crystals, which are widely used in semiconductors, photovoltaics, lasers and optical devices, such as the preparation of silicon single crystals, sapphire single crystals and gallium arsenide single crystals. 

Ceramics, one of the greatest inventions in human history, have evolved over thousands of years from simple household items to critical materials in industries, technology, and art. From everyday tableware and teaware to architectural tiles and sanitary ware, and even key components in aerospace and electronics, ceramics are ubiquitous. Behind the thriving modern ceramics industry, an "invisible hero" plays a vital role: Ammonium Metatungstate (AMT). Though unfamiliar to the general public, AMT significantly enhances ceramic performance and drives industry progress.

High-temperature melting usually involves the preparation of metals, rare earth elements or special alloys with high melting points, and the process environment is harsh, and the requirements for container materials are extremely high. With its unique properties, tungsten crucible has become the preferred container for high-temperature smelting, and its application involving metallurgy, aerospace, rare earth smelting and other industries.
