Titanium boride powder, TiB, titanium diboride powder, TiB2, titanium(II) boride, titaniumboride(tib2), titanium boride, 99.5% (metals basis), CAS# 12045-63-5
Chemical Name: Titanium boride / Titanium diboride
Chemical Formulas: TiB / TiB2
a) High purity product. Stable in HCl and HF acid. Excellent densification properties. High hardness
b) Titanium DiBoride (TiB2) is the most stable of several titanium-boron compounds. The material does not occur in nature but may be synthesised by carbothermal reduction of TiO2 and B2O3.
c) As with other largely covalent bonded materials, TiB2 is resistant to sintering and is usually densified by hot pressing or hot isostatic pressing. Pressureless sintering of TiB2 can achieve high densities but liquid forming sintering aids such as iron, chromium and carbon, are required.
- Titanium Boride/ Diboride (TiB2) Nominal Chemical Purities Available:
a) 99.5%.
b) Chemical Composition: Ti= 67-69%, and B= 29-32%
Targets, single crystal, pieces, and powder granulations of 150X 325 mesh, 325 mesh X 10 microns, and 325 mesh by down.
