Zirconium Diboride Powder / ZrB2 Powder (99%, 40 um, Hexagonal)

Zirconium Diboride Powder

Introduction:

Zirconium diboride (ZrB₂) is a refractory ceramic compound made up of zirconium and boron. It belongs to a class of materials known as Ultra-High Temperature Ceramics (UHTCs), which have outstanding properties that allow them to withstand extreme thermal, mechanical, and chemical conditions. ZrB₂ has a high melting point of around 3,300°C (5,992°F), making it one of the highest melting-point materials known. The powder form of ZrB₂, characterized by its fine particles and high surface area, is particularly valued in industries that demand materials capable of operating under extreme conditions, such as aerospace, defense, and energy sectors.

The powder form of ZrB₂ is commonly used as a precursor for creating high-performance ceramics, coatings, and composites, as it can be sintered or processed to produce dense, durable materials. ZrB₂ also exhibits high hardness, good electrical conductivity, and oxidation resistance, making it suitable for a wide range of applications in industries that require high temperature, wear, and corrosion resistance.

Properties of Zirconium Diboride (ZrB₂) Powder

High Melting Point and Thermal Stability:

ZrB₂ has one of the highest melting points among known materials, around 3,300°C, which makes it suitable for extreme temperature applications such as aerospace and nuclear industries.

It retains excellent thermal stability even at high temperatures, meaning it can withstand prolonged exposure to heat without significant degradation.

Hardness and Mechanical Strength:

ZrB₂ powder is known for its exceptional hardness and mechanical strength. It is highly resistant to wear, abrasion, and mechanical damage, making it ideal for applications involving high-stress conditions.

Electrical Conductivity:

ZrB₂ exhibits good electrical conductivity, which is relatively rare for ceramic materials. This makes it suitable for electronic applications, including electrodes and conductive coatings.

Oxidation and Corrosion Resistance:

ZrB₂ is highly resistant to oxidation and corrosion, especially when exposed to harsh environments like high temperatures or reactive chemicals. This makes it an excellent material for applications in harsh or aggressive environments, such as in the aerospace and nuclear industries.

Thermal Conductivity:

ZrB₂ has a high thermal conductivity, allowing it to transfer heat effectively. This is advantageous in applications where heat dissipation is crucial, such as in aerospace components.
