Import 325 Mesh Wollastonite Powder For Ceramic Glaze — Buy in wholesale FOB from Supplier in China

325 Mesh Wollastonite Powder For Ceramic Glaze from Shenyang Huakuang is a calcium silicate mineral (CaSiO3) engineered to reduce sintering temperature and shorten firing cycles in ceramic manufacturing. The supplier emphasises lower Fe content, reduced LOI, fewer surface defects, improved shrinkage control, and faster drying times as key advantages over competing materials. The 325 mesh fineness ensures adequate surface area for glaze reactions while maintaining sufficient coarseness to avoid excessive suspension viscosity in mill additions. Typical supply packaging of 25 kg bags or 1 MT bulk bags targets Southeast Asian and Middle Eastern ceramic markets, though buyers must confirm current availability and pricing directly with the supplier.

The fluxing properties of this wollastonite derive from its calcium silicate composition, which begins to form low-melting eutectics with silica and alumina at temperatures below pure feldspar-fluxed systems. In practical glaze formulation, this allows partial replacement of whiting (calcium carbonate) and feldspar, with the added benefit that wollastonite does not release CO2 on decomposition (unlike whiting), eliminating a major source of glaze blistering and pinholing. The lower thermal expansion coefficient of wollastonite-bearing glazes improves resistance to thermal shock and reduces crazing tendency in fast-fire wall tile and sanitaryware applications. Standard industry practice suggests addition rates of 10-25% in glaze batches, though optimal percentage depends on base glaze composition and firing curve.

Ceramic glaze manufacturers, refractory producers, and craft ceramic studios represent the primary buyer segments for this material. The improved embryo strength cited by the supplier translates to lower breakage rates during green handling and kiln loading, directly reducing production waste. The powder's effect on reducing mud viscosity benefits slip-cast production by improving drain rates and reducing drying defects. Importers should note that while the supplier lists CIF major ports as a typical term, no specific pricing, confirmed MOQ, or lead-time data is available in the listing. Direct negotiation is required to establish these parameters, and buyers should request trial quantities for glaze compatibility testing before bulk commitment.

Shenyang Huakuang operates from Shenyang, Liaoning Province, China, with the same registered address and postal code 10000 as the supplier's other listing, confirming this is a single company with multiple product presentations rather than a separate entity. The harbor trust tier and 0.00% response rate with zero average response hours apply identically, indicating no platform-mediated quoting history. The supplier's profile does not differentiate between the two wollastonite listings in terms of production facility, quality control laboratory, or management structure, so buyers should treat claims in each listing as applying to the same operational base.

The company positions itself specifically as a wollastonite specialist with advantages framed around iron control, LOI reduction, and process improvements for ceramic manufacturers. No information is provided about mining rights, beneficiation plant capacity, vertical integration from ore to powder, or environmental compliance certifications. The emphasis on Southeast Asian and Middle Eastern markets suggests existing export experience, though reference customers or distributor networks are not named. Buyers should request company registration documents, export licence verification, and any ISO or industry-specific quality certifications before advancing beyond initial enquiry.
