This product is designed for researchers requiring a high-solid-content, pre-oxidized carbon precursor for graphene oxide synthesis. Oxidized graphite (paste) with a 40% solid content is formulated as a non-flowing, partially black paste with slightly acidic properties, offering a high degree of oxidation that facilitates efficient conversion into stable graphene oxide dispersions through ultrasonic exfoliation. As a key intermediate in the production of low-dimensional carbon materials, it is commonly used in the preparation of graphene-based composites, electrode materials for supercapacitors, and membrane separation research. The material requires sealed storage to maintain its chemical integrity. Available in pack sizes from 20 g to 1000 g, it supports both small-scale laboratory trials and larger experimental batches.
