Business Division
Hanchang develops and supplies the highest quality functional materials to lead a sustainable future through innovative material development.
Development History
-
01 Manganese oxide
As a primary material for the synthesis of soft ferrite, we have produced high-purity Mn3O4, the only one in Korea, based on our own patent.
-
02 Metal manganese powder
This is the material for manganese welding rods, of which we are the sole manufacturer in Korea.
-
03 Glass beads
We are the only company in Korea to produce premium products used as materials for night reflective paint for road markings.
-
04 TPA catalyst
We developed a catalyst for the production of terephthalic acid.
-
05 Zinc sulfate
It is a primary material for the synthesis of zinc compounds.
-
06 Cobalt sulfate
A basic cobalt compound for pigments, batteries, and feed.
-
07 CZO+Pt Catalyst for hydrogen production
A catalyst used to produce hydrogen, providing high catalytic activity.
-
08 CMD, a material for secondary batteries
It is used as an anode material for high-capacity lithium cells for electric vehicles (EVs) and hybrid electric vehicles (HEVs).
-
09 ZnBr-RFB electrolytes materials
Electrolytes for chemical flow batteries (ZnBr-RFB), used in energy storage systems.
-
10 V-RFB electrolyte
Electrolytes for chemical flow batteries, for efficient energy storage and release.
-
11 Solid Oxide Fuel Cell anode materials
- LSM (Lanthanum strontium manganese oxide): An anode material used in solid oxide fuel cells (SOFCs), with high conductivity and durability.
- LSCF (Lanthanum strontium cobalt iron oxide): Another anode material for SOFCs, with excellent conductivity and electrochemical performance.
