Quality Control

Our Barium Titanyl Oxalate Tetrahydrate is manufactured under controlled conditions to ensure batch-to-batch consistency critical for downstream ceramic performance. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD), thermogravimetric analysis (TGA), and inductively coupled plasma optical emission spectrometry (ICP-OES). A comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and physical characteristics is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). To prevent caking and decomposition, the container must be kept tightly sealed in a dry environment. Keep away from incompatible materials such as strong acids and strong oxidizers.
