The RTK‑H fused cast beta alumina block is supplied by Henan Reftech Industrial Co., Ltd. in China. This grade consists of nearly 100 % beta alumina, giving it a dense microstructure and strong resistance to spalling. Its anti‑spalling characteristic is complemented by excellent corrosion resistance to alkali vapour, making it suitable for harsh refractory environments. The block contains minimal vitreous phase and will not contaminate molten glass.
In the refractory industry beta alumina blocks are valued for their low porosity, typically below 2 %, and high compressive strength, often around 150 MPa. The material’s thermal conductivity is usually about 2.5 W · m⁻¹ · K⁻¹, which helps maintain temperature uniformity in furnace linings. Standard block dimensions are 100 × 100 × 100 mm with a tolerance of ±1 mm, and a typical density of 3.6 g · cm⁻³. These typical parameters align with ISO 11561 requirements for high‑temperature refractories.
Common applications include the superstructure and crown of oxy‑fuel furnaces where low slag formation is critical. Importers such as glass manufacturers and high‑temperature furnace builders often source this product in bulk palletised loads. Buyers should confirm the minimum order quantity, lead time and preferred Incoterms directly with the supplier before placing an order.

Before placing an order with Henan Reftech, verify the company’s business registration and request a copy of its latest corporate licence. Ask for a material certification that confirms the beta alumina purity and density of the RTK‑H blocks, and compare the data with the typical values provided here. Because the platform records a zero response rate, it is prudent to obtain recent references or factory photos to assess production capability.
Discuss the preferred Incoterm for shipment, such as FOB Xinmi port or CIF Shanghai, and ensure the supplier can arrange container loading of palletised blocks. Since lead‑time is not disclosed, request a realistic production schedule and confirm whether the supplier can meet your required delivery window. Payment terms are typically negotiated on a letter of credit basis, but clarify any advance payment requirements before signing a contract.
Arrange for a third‑party inspection agency to sample the blocks before loading, focusing on dimensions, compressive strength and porosity. Request the test reports for ISO 11561 compliance, thermal conductivity and corrosion resistance to alkali vapour. Ensure that the supplier provides a certificate of origin and a packing list that matches the agreed quantities, to facilitate customs clearance in the destination country.
