Zero-Expansion Silica Bricks from China
Zero-expansion silica bricks are published in Sinosteel Luonai’s iron-and-steel refractory catalog. Because the public page does not state a universal specification, procurement begins with the equipment, lining zone, thermal cycle and contract requirements.

Published catalog reference. Final grade, dimensions, properties and availability are confirmed against the RFQ. Official source.

Procurement FAQ
Questions buyers often ask
Does zero-expansion mean the brick has no dimensional change under every condition?+
The official name should not be treated as a universal performance guarantee. The exact grade, test method and specified limits must be confirmed in the contract.
Can it replace a conventional silica brick directly?+
Not without reviewing the equipment design, current grade, dimensions, joints, heat-up practice and operating conditions.
What should be included in the RFQ?+
Send the application, existing specification, drawings, quantity, inspection standard and project schedule.
