Cristobalite Powder
Cristobalite Powder supplied by Lianyungang Changtong Silica Powder Co., Ltd. is a high‑purity silica mineral with a SiO₂ content of 99.5 %. The product is offered in three grades - M3000, M4000 and M6000 - each identified by its mesh designation. Impurity levels are low, with P₂O₅ at 0.0002 %, CaO and MgO each at 0.01 % and Al₂O₃ at 0.15 %. The powder is packed in either 25 kg paper bags or 1000 kg bulk bags, allowing 20‑24 tonnes to be loaded into a standard 20‑foot container.
In the foundry and investment‑casting sectors Cristobalite is valued for its thermal stability and minimal expansion at temperatures above 1 200 °C. Typical bulk density for this grade of silica is around 0.45 g cm⁻³ and moisture content is kept below 0.5 % to preserve flowability. Standard industry practice specifies a particle‑size distribution centred around 3 µm for M3000, 4 µm for M4000 and 6 µm for M6000, with a tolerance of ± 0.5 µm. The white powder complies with common refractory specifications such as ASTM C150 and ISO 9001, although the supplier’s certification documents should be requested.
Typical buyers include casting foundries, ceramic manufacturers and refractory producers who require consistent silica purity for precision moulds. The supplier states that a free sample ranging from 5 kg to 25 kg can be provided on request, after which bulk orders are arranged according to the buyer’s preferred Incoterm. Prospective importers should confirm the exact MOQ, lead time and payment terms directly with the company before placing an order.

Sourcing Cristobalite Powder from Lianyungang Changtong Silica Powder Co., Ltd. - China Import Guide
Before finalising a purchase, importers should verify the grade (M3000, M4000, M6000) and request the latest chemical analysis and particle‑size distribution reports. The harbour‑tier verification indicates that the company’s business licence has been cross‑checked, but the zero response rate means communication may be slower, so establishing a clear point of contact early is advisable. Confirm that the free‑sample policy matches your trial requirements.
Shipping from Lianyungang port is typical for this supplier; buyers should agree on Incoterms such as FOB Lianyungang or CIF Shanghai, and clarify the expected lead time, which is not disclosed in the listing. Payment methods commonly used in the region include T/T in advance or a confirmed irrevocable L/C at sight; these terms should be documented in the contract. Ensure that container loading plans respect the 20‑24 tonne capacity to avoid unexpected freight charges.
Quality assurance can be reinforced by arranging a pre‑shipment inspection with a third‑party laboratory, focusing on purity, moisture and particle‑size compliance. Request certificates of analysis, XRF reports and thermal‑expansion test results before loading. Keeping records of these documents will facilitate customs clearance and protect against non‑conformity disputes.
