Zinc Refiner Tablet Melt Refining for Zinc & Zinc Alloys
The solid, tablet-form refiner for molten zinc and zinc alloys — plunged into the melt to help clean it of inclusions before casting. Pairs with our Zincflux and degassing tablets.
Chelora Chemicals delivers Zinc Refiner Tablets to zinc foundries, die casters and remelters across the United States, with a batch COA and SDS on every consignment.

From metal charge to cast product
The refiner tablet works in the melt, between charging and casting. Each neighbouring stage below is a product on this site.

What the refiner tablet is used for
A Zinc Refiner Tablet is a solid refiner added to molten zinc or zinc alloy to clean the melt before pouring. Foundry research on zinc and zinc-aluminium alloys describes solid refiners as agents that protect the melt from gas pick-up and oxidation and purify it of inclusions, which supports cleaner, denser castings.
Tablet form makes dosing simple: the tablet is plunged below the surface so it reacts inside the melt rather than floating on top. The exact composition varies by grade and is proprietary, so we confirm it on the batch SDS instead of quoting one formula here.
Typical use points
- Zinc alloy foundries. Refining the melt before pouring into moulds.
- Zinc die casting. Keeping the holding furnace melt clean.
- Remelting of zinc scrap. Treating melts built from returns and skimmings.
- Zinc-aluminium foundry alloys. Melt refining ahead of casting.
How it differs from a flux
A surface flux such as Zincflux works at the dross layer. A refiner tablet works inside the melt. Many plants use both. For aluminium melts use grain refiner tablets or degassing tablets.

Importing into the United States
Refiner tablets are chemical mixtures, so each component needs a TSCA Inventory check. Under TSCA section 13 the importer of record, or its authorised agent, certifies each shipment to US Customs and Border Protection. We agree in writing who files that certification before the first consignment moves.
Which party carries that duty follows the Incoterm. On FOB, CFR or CIF terms it is usually the US buyer; on DDP terms it can be the seller or its agent. Safety data sheets and labels are supplied to OSHA's updated Hazard Communication Standard.
| Item | How it works |
|---|---|
| Delivery points | Any nominated US plant, warehouse or port of discharge |
| Incoterms quoted | FOB · CFR · CIF · DDP |
| Importer of record | Agreed in writing before the first shipment |
| TSCA certification | Section 13 certification filed at entry |
| Documentation | Batch COA, SDS, packing list, certificate of origin |
Note: regions describe where we deliver, not where we hold inventory. Lead time depends on producer scheduling and transit, confirmed in the quotation.
How we supply Zinc Refiner Tablets
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. Tablet grade, size and composition need to match your melt size and alloy, which shapes how we select producers on this line.
We place your order with whichever qualified producer best matches your grade, price point and delivery window, and confirm US import requirements before booking.
- Composition confirmed before we quote. Components and CAS numbers come from the SDS, not assumptions.
- TSCA status settled first. We agree who files the section 13 certification before shipment.
- Batch traceability to the producing plant. Chain-of-custody records on request.
- One desk for the melt shop. Order alongside Zincflux, degassing tablets and ceramic foam filters.
Pack format matched to your plant
Tell us your preferred format and handling route and we will quote and classify to it.
Format confirmed at quotation
Pack type and tablet size are agreed against your handling method and the grade supplied.
Incoterms to suit you
Quoted on the Incoterm your purchasing team works to, with documentation filed before booking.
Trial / sample quantities
Small quantities for furnace trials before a commercial order is placed.
Keep tablets dry — ventilate the melt shop
Hazard classification depends on the grade. The safety data sheet supplied with your batch is the authoritative document.
Hazard information
GHS signal word, H-statements and transport class are listed on the SDS for the specific grade and are not repeated here, so nothing on this page can contradict your batch document.
Storage
Keep in closed containers in a cool, dry, well-ventilated area, away from moisture and incompatible materials listed on the SDS. Damp tablets can behave differently in a hot melt.
Handling
Dry the tablet and the plunging tool before use, plunge below the melt surface as the producer instructs, use local exhaust ventilation, wear eye and skin protection, and follow your site's hot-metal procedures.
Transport
We confirm and document the exact classification and routing for your shipment and destination before booking.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Grade, tablet size and composition basis confirmed against your melt and alloy before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and TSCA data checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with chain-of-custody records on request.
How melt refining works for zinc
Foundry studies of zinc and binary zinc-aluminium alloys report that refining the melt before pouring improves casting quality, because the refiner purifies the melt of inclusions and protects it against gas pick-up and oxidation. Cleaner melt gives denser castings and better ductility.
Refining is separate from grain refining. Grain refiners for zinc alloys, such as titanium-bearing master alloys, change solidification structure, while a melt refiner cleans the metal itself. Your plant may use both with master alloys and alloying tablets.
We do not publish operating dosages here; this is background only. Full technical documentation accompanies every shipment, and process detail is best confirmed with our technical desk.
