Hafnium diboride is an ultrahigh temperature ceramic composed of hafnium and boron. It has a melting temperature of about 3250 degrees Celsius. It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and zirconium diboride. It is a grey, metallic looking material. Hafnium diboride has a hexagonal crystal structure, a molar mass of 200.11 grams per mole, and a density of 10.5 grams per cubic centimeter. Hafnium diboride is often combined with carbon, boron, silicon, silicon carbide, and/or nickel to improve the consolidation of the hafnium diboride powder (sintering). It is commonly formed into a solid by a process called hot pressing, where the powders are pressed together using both heat and pressure. The material has potential for use in hypervelocity reentry vehicles such as ICBM heat shields or aerodynamic leading-edges, due to its strength and thermal properties. Unlike polymer and composite material, HfB2 can be formed into aerodynamic shapes that will not ablate during reentry. Hafnium diboride is also investigated as a possible new material for nuclear reactor control rods. It is also being investigated as a microchip diffusion barrier. If synthesized correctly, the barrier can be less than 7nm thick.

Nano barium titanate is an important basic raw material in the electronic ceramic components industry, known as the "pillar of the electronic ceramic industry", and is also one of the most widely used and most consumed important raw materials in electronic ceramics.

Widely used in plastics, adhesives, textiles, rubber, modified copolymers and so on.

Rubidium hydroxide is generally used as raw materials for the preparation of metal rubidium and various rubidium salts, catalyst production, micro high-energy batteries, raw materials containing rubidium single crystals, special glass and ceramic industries.

It is used as the adhesion agent and colorant of enamel, the pigment of ceramics and glass, the production of nickel zinc ferrite in the production of magnetic materials, the manufacture of nickel salt raw material, nickel catalyst and its application in metallurgy and picture tube, as well as electronic component materials, catalysts, enamel coatings and battery materials.
