Three-low fireclay brick refers to low porosity, low iron, and low creep. They are made of high-quality raw materials, three-stone raw materials, ultra-fine composite powder, and specific additives through high-pressure forming and high-temperature sintering. They have strong high-temperature corrosion resistance and medium and high-temperature creep rates. high compressive strength and high refractoriness under load.

Low porosity clay brick characteristics
1. Low apparent porosity and strong compactness.
2. Good permeability and erosion resistance.
3. High-temperature strength and long service life.
