Products Introduction

Select tantalum powder of appropriate particle size with purity above 99.9%, add a small amount of specific additives, and stir thoroughly. The processed tantalum powder is put into the mold and compacted into a green body under high pressure. This can make the density of the green body uniform. After demoulding, a preliminary inspection is carried out. The green body is first heated to make the tantalum material plastically better, and then fixed on the spinning core mold. The rollers of the spinning machine apply pressure and rotate according to a specific trajectory, and precise control makes the thickness of the crucible wall uniform. The surface is then treated to improve quality and corrosion resistance through polishing. Finally, from visual inspection for defects, to measuring dimensions with professional measuring tools, to testing physical properties such as density and hardness, only if all indicators are qualified can you enter the packaging and delivery process!

Application

Spinning tantalum crucibles are mostly used in the metallurgical industry, the electronic semiconductor field, scientific research experiments, optical glass manufacturing, and other fields. Due to its excellent high temperature resistance, corrosion resistance, thermal stability, and thermal conductivity, it has an indispensable place in these fields. For example, the spinning tantalum crucible can ensure that the metal purity is not affected during the extraction process of rare metals; During the Czochralski growth process of single crystal silicon, the spinning tantalum crucible is used as a reaction vessel to provide an ultra-clean environment to avoid impurities contaminating the crystal; and in scientific research experiments, the spinning tantalum crucible can help scientific researchers obtain accurate and reliable test results. During the melting process of optical glass, the good thermal conductivity and high purity characteristics of the spinning tantalum crucible enable it to accurately control the melting temperature while preventing impurities from contaminating the glass.
