Zirconium Diboride Nanoparticles

Zirconium diboride (ZrB2) is an ultra-high-temperature ceramic (UHTC) possessing ... Carbothermal reduction produced nanosized crystalline ZrC grains on the surface of ZrB2 powder.

Modification of ZrB2 powders by a sol-gel ZrC precursor—A new approach for ultra-high-temperature ceramic composites

A simple method of integrating a powder processing technique with a sol–gel process to produce ultra-high-temperature ceramic (UHTC) composites is reported.

ZrB2 powder was treated with a zirconium oxide-carbon sol–gel coating.

Detailed refinement of carbon content in the sol–gel coating was necessary to control the oxide reduction on the ZrB2 surface while providing intrinsic carbon for the nanoparticle sol–gel phase.

Microstructures and crystalline phases were analyzed using TEM, SEM, and XRD.

It was found that carbothermal reduction of ZrO2 to form nano ZrC can be completed on the surface of ZrB2 at 1450 °C.

The sol–gel coating creates a homogenous mix of ~200 nm ZrC in close proximity to the ZrB2 surface.

Densification of the ZrB2-ZrC composite can be achieved by spark plasma sintering at 1800 °C.

The amount of carbon added to the sol–gel precursor needs to be carefully tailored to dictate the final porosity and grain size of sintered composites.

Synthesis of Zirconium Diboride (ZrB2) Nanoparticles by Sol-gel Method

CHECKLIST:

Zirconium Propoxide (Zr(OPr)4), Boric Acid (H3BO3), Sucrose (C12H22O11), Acetic Acid (CH3COOH), Methanol (CH3OH), Acetylacetone (C5H8O2), Water

STEP 1. Add Zirconium Propoxide (6.3ml) and Acetylacetone (1.2ml) in 25ml of Methanol.

Stirrer it at room temperature.

STEP 2. Add 4ml of water dropwise and stirred for 30 minutes at room temperature.

STEP 3. In another beaker, Add Boric Acid (2.5g) and Sucrose (2.9g) in 45ml of Acetic Acid.

Stirrer for 30 minutes and 80°C.

STEP 4. Add Zirconium Propoxide solution into Boric Acid solution and stir for 4 hours at 60°C to form the wet gel.

STEP 5. Dry the formed wet gel at 120°C for 3 hours to form the final precursor.

STEP 6. Now grind the dried sample with mortar-pestle.

And Calcine it at 1550°C for 4 hours at a slow ramping rate of 2-3°C/min.

RESULTS

Finally, Zirconium Diboride (ZrB2) Nanoparticles are formed as Gray color after calcination.

Factors Affecting Synthesis

Calcination (in STEP 6) can also be done in 3 steps.

First 30-800°C with 5°C/min, then 800-1200°C with 3°C/min for 2 hours and finally 1200-1550°C with 2°C/min for another 2 hours.

The cooling rate should be 5°C/min.

This elaborated calcination can increase the crystallinity of the formed Zirconium Diboride (ZrB2) Nanoparticles.

Diffusion barrier characteristics of-zirconium-diboride-films-

Low resistivity and fully conformal ZrBi thin films are deposited by remote plasma chemical vapor deposition using zirconium tetrahydroborate, Zr(BH4)4.

The problems with thermal CVD using this precursor -excess B incorporation, oxygen contamination, and high resistivity - are eliminated by injecting atomic hydrogen from a remote microwave plasma source onto the substrate.

Using this technique, the films are stoichiometric, have ∼40 μΩ-cm resistivities, < 4 at.% oxygen contamination, and are fully conformal in deep trenches and vias.

We show that a 50 nm thick ZrB2 film on c-Si (100) prevents Cu in-diffusion after 1-hour of annealing at 650°C.
