High Purity Alumina Hexagonal Ceramic Tiles
Description
Technical Parameters
Products Description
High purity alumina hexagonal ceramic tiles are made of high-purity alpha alumina as the substrate, forming a completely dense interlocking corundum crystal structure without low melting point impurities. There are three mainstream purity levels (92%, 95%, 99%) that can be used to match different working temperatures and media corrosiveness. The standard side length range is 12mm to 20mm, and the thickness range is 3mm to 15mm. Unlike the wear-resistant hexagonal lining bricks of bulk material chutes, this refractory grade product focuses on high temperature volume stability and slag resistance, maintaining stable physical and chemical properties under long-term continuous operation at 1500-1700 ℃.
The hexagonal profile achieves seamless interlocking assembly, eliminating the direct gaps that allow slag and corrosive fumes to penetrate the backing layer. The size tolerance of each tile is consistent to ensure a tight fit between units and no significant height difference after installation. Its low thermal expansion coefficient matches the thermal deformation rhythm of the steel furnace shell, avoiding cracking and peeling of the furnace lining caused by uneven cold and hot deformation.
Advantages
The geometric structure of ceramic lining materials plays a crucial role in system performance. The hexagonal structure used in high purity alumina hexagonal ceramic tiles has several engineering advantages over traditional shapes.
1. Interlocking layout reduces installation gaps, which is a common weakness of wear-resistant lining systems. Reducing the gap means a lower risk of material infiltration and edge erosion.
2. This shape distributes mechanical stress more evenly across the entire surface. This reduces local impact concentration and extends the overall lifespan of the lining system.
3. Hexagonal tiles improve adaptability to curved or irregular surfaces. This makes it easier to apply ceramic protection in complex industrial equipment that is not suitable for tablets.
These advantages collectively improve the stability of the system and reduce long-term maintenance requirements.

Manufacturing process and quality control
The production of high purity alumina hexagonal ceramic tiles involves multiple precision control stages to ensure consistent performance:
Selection of high-purity alumina raw materials
Fine powder grinding and homogenization
Precision press in hexagonal mold
High temperature sintering (>1500 ° C)
Control cooling to stabilize the structure
Surface treatment and dimensional inspection
Mechanical strength and wear test
Each batch of products undergoes strict quality inspection, including density testing, hardness measurement, and dimensional verification. This ensures consistent performance across different production batches.
Installation precautions
Proper installation is crucial for maximizing the performance of ceramic lining systems. According to application requirements, these tiles can be installed using epoxy resin adhesives or mechanical fastening systems.
Before installation, the surface must be cleaned and leveled to ensure optimal adhesion. During the placement process, attention should be paid to alignment to maintain uniform coverage.
After installation, high-purity alumina hexagonal tiles form a continuous protective layer, effectively protecting the underlying equipment from wear and corrosion.
