Storage method: This product should be sealed and stored in a dry and cool environment. It should not be exposed to air for a long time to prevent moisture from causing aggregation, affecting dispersion performance and usage effect. In addition, it should be avoided from heavy pressure and not in contact with oxidants. It should be transported as ordinary goods. 
Product features: It has metallic luster crystals, high melting point, wear resistance, and high hardness. 
Purpose: 
1. Tantalum boride biological coating, a dense and large-area boron rich structure tantalum boride coating. This coating is non-toxic, has good biocompatibility and osteoinductivity, high resistance to body fluid corrosion, and can effectively prevent the precipitation and diffusion of toxic ions inside medical implant materials 
2. Used for ultra-high temperature ceramic matrix composites, ultra-high temperature borides mainly include hafnium boride (HfB2), zirconium boride (ZrB2), tantalum boride (TaB2), and titanium boride (TiB2). Currently, research on zirconium boride (ZrB2) and hafnium boride (HfB2) is the most concentrated. Boride ultra-high temperature ceramics are composed of strong covalent bonds and have characteristics such as high melting point, high hardness, high strength, low evaporation rate, high thermal conductivity
