Potassium Dichromate Supplier in Malaysia
- Also known as
- K2Cr2O7
- Potassium Bichromate
- Dipotassium Dichromate
Potassium dichromate supplier for laboratory oxidising work, chrome tanning and industrial process oxidation in Malaysia. Also traded as potassium bichromate and K2Cr2O7 (CAS 7778-50-9), it is a bright orange crystalline hexavalent chromium oxidiser distinct from sodium dichromate.
Commercial options include technical-grade crystals for leather tanning, wood staining and ceramic pigmentation, and analytical or reagent grades for volumetric analysis and chemical oxygen demand (COD) methods. Assay and packing are confirmed against the requirement with the quotation.
Buyers use potassium dichromate where a strong Cr(VI) oxidiser is named on the process or laboratory method. It is not a food additive and is not E224, which belongs to potassium metabisulphite. Industrial demand for hexavalent chromium compounds continues to face substitution pressure, so enquiries should state the real process need.
Send the required technical or reagent grade, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

Potassium Dichromate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical-grade potassium dichromate crystals | bright orange crystalline solid | — | Chrome tanning, wood staining, ceramic pigmentation and other industrial process oxidation where a technical K2Cr2O7 grade is specified. | Confirm the required pack format with the quotation. |
| Analytical or reagent-grade potassium dichromate | orange crystalline solid or crystalline powder | — | Laboratory oxidising work, volumetric analysis and chemical oxygen demand (COD) methods that name potassium dichromate on the procedure. | Confirm the required pack format with the quotation. |
| Purified crystalline grade for process oxidation | crystalline solid | — | Process oxidising steps and specialty manufacturing where a cleaner potassium dichromate grade is preferred over a broad technical cut. | Confirm the required pack format with the quotation. |

Common questions about potassium dichromate
Is potassium dichromate the same as sodium dichromate?
No. Potassium dichromate is K2Cr2O7 (CAS 7778-50-9). Sodium dichromate is a different dichromate salt with its own identity, solubility and process fit. State potassium dichromate by name so the enquiry is not mixed with sodium dichromate.
Which grade should I request for laboratory or COD work?
Analytical or reagent-grade material is commonly selected for volumetric analysis and COD methods that name potassium dichromate. Technical crystals are more often used for industrial tanning, staining or process oxidation. Send the method or process specification so the quotation can match grade.
Is potassium dichromate a food additive or E224?
No. Potassium dichromate is an industrial and laboratory hexavalent chromium oxidiser. E224 identifies potassium metabisulphite, a different chemical used as a food preservative. Do not treat dichromate grades as food additives.
What is potassium bichromate?
Potassium bichromate is an established alternate name for potassium dichromate (K2Cr2O7). The enquiry should still state technical or reagent grade, application and quantity.
What details are needed for a potassium dichromate price enquiry?
Provide the required grade, application, any assay or impurity limits, quantity and delivery location. Mention preferred packing and documents so the quotation can cover the full requirement.
Can packing and documentation be confirmed with the quotation?
Yes. List the preferred pack format and any required safety or specification documents in the enquiry. Available packing and documentation are confirmed for the quoted grade.
