Q1: Do you accept sample order? A: Yes, we accept small order from 10g, 100g, and 1kg for your evaluation quality of our goods.
Synthesis produces single crystal grains or amorphous spheres, each of them a primary particle. Let several of them touch and bond, and they form a larger unit — an agglomerate. Agglomerates differ in how firmly they are held together. In a soft agglomerate the primary particles are bound mainly by weak physical forces such as van der Waals attraction, and ultrasound or another source of external energy can separate them again. In a hard agglomerate the contact points have been welded shut by chemical bonds or by sintering, and no ordinary dispersion step will prise them apart.

Black, phase-pure Fe₃O₄ is the preferred grade for lithium-ion battery anode applications. A reddish-brown color indicates that the powder surface has been partially oxidized (to Fe₂O₃), which compromises electrochemical performance.
Titanate Nanotubes Powder is attracting increasing attention in advanced materials research because its nanotube morphology combines a high specific surface area, surface reactivity, photocatalytic activity, ion-exchange capability, and useful electrochemical properties. According to SAT NANO, its Titanate Nanotubes Powder is supplied with 99% purity, a 10–30 nm diameter, a length greater than 1 μm, and a specific surface area of 200–300 m²/g.
Scope: water/alcohol dispersion of nano α-Fe₂O₃ powder and evaluation of dispersion quality (TEM/SEM observation) Assumptions: the purpose is to evaluate dispersion quality and primary particle morphology; particle size is nano-scale. For high-solids slurry preparation, increase the solids content and adjust dispersant dosage accordingly.
