Product Overview
Selected mullite and cordierite as the main raw materials, using advanced production technology,
specializing in the manufacture of ceramic, powder metallurgy and other kiln setter plates, shed plates,
saggers, muffle plates, slide rails, backing plates, pillars and other kilns with tools.

Product Features
1. The refractoriness is higher than that of cordierite.
2. Small thermal expansion coefficient, good thermal shock stability, long service life, no sudden breakage.
3. No oxidation, no dirt or slag, and no pollution to ceramic products during use.
