Primet’s Process Technology for Battery Materials
Primet has developed process technology for creating precise, highly engineered particles of nanometric and micrometric sizes in a variety of solid materials.
Primet Develops Tetragonal Barium Titanate for Printable Electronics
A pure tetragonal phase BaTiO3 with mean particle sizes less than 100nm is highly sought after because it can enable next generation capacitor technology.
Technical Notes
Technical Note 1 - Hydrophobicity Characterization of Silane-Treated Titania
Samples of six different lots of high purity rutile titania produced by Primet’s Nano-Scission™ process were treated with an alkoxysilane and characterized with respect to hydrophobicity. Prior to silane treatment, the BET specific surface area of these materials ranged from 62 to 116 m2/g and the equivalent spherical diameter (ESD) from 22.7 to 12.1 nm.
Technical Note 2 - Photostability of Primet Titanias
This note presents the results of three different Primet titanias. Results are summarized in Table 1.
Technical Note 3 - Nano-Mica
Primet has synthesized nano dimensioned mica from a muscovite ore material. Atomic Force Microscopy (AFM) of the processed material showed that the particles retained the platelet morphology characteristic of mica and that, in general, they had a diameter of approximately 1micron and thicknesses ranging from 10 to 30 nm.
Technical Note 4 - Nano-Silicon
Primet’s Nanoscission™ technology has been used to synthesize nano-silicon with platelet morphology and primary particle size as small as 20 nm. Particle size and morphology were evaluated using specific surface area (BET method), acoustic spectrometry (Dispersion Technology’s DT-1200) and SEM. Table 1 summarizes specific surface area and acoustic spectrometry results for five different lots. Figures 1 through 4 present SEM results for lots NS4 and NS5.
DT-1200 Acoustic and Electroacoustic Spectrometer
Dispersion Technology’s DT-1200 Electroacoustic Spectrometer is used to measure the particle size distribution of slurries.
