Zirconia Toughened Alumina Tiles

1. Product Overview

ZTA ceramic tiles are high-toughness anti-wear lining components developed independently. Mixed alumina and stabilized zirconia powder are pressed isostatically and sintered by gradient heating to form reinforced microcrystals. Designed for ore-impacted hoppers, chutes and cyclones, flat, interlock and dovetail types support bonding and welding installation.

F – Core Features

21%-23% zirconia blended matrix suppresses crack spread under impact

Index: HRA 88–90, compressive strength ≥1700MPa, toughness twice 95% alumina tiles, wear loss ≤0.22cm³

Stepwise firing removes internal pores and hidden microcracks

Interlock splicing prevents local tile detachment during material scouring

Inert crystal structure resists mild acid, alkali and mid-temperature flue gasAll indicators pass third-party tests with traceable batch records.

A – Advantages

Common alumina liners crack easily against massive ore hits despite high hardness. Zirconia particles absorb impact energy to inhibit crack expansion. Even raw material mixing and precise firing ensure uniform performance without fragile areas. Smooth surfaces reduce material adhesion and blockage, compatible with regular lining construction.

B – User Benefits

Mining, cement and port bulk transport facilities greatly extend lining service cycles after switching to these tiles. Less frequent partial replacement shortens production shutdowns and cuts maintenance labor costs. Modular layout speeds up field installation, while corrosion resistance prevents premature liner failure and lowers long-term spare part expenditure.

E – EEAT Credibility

Located in Zibo advanced ceramic base, our factory owns automated pressing and sintering lines with ISO9001 certification and professional composite ceramic R&D staff. Our liners export to Central Asia, Southeast Asia and European mining zones, serving over 65 manufacturers. An iron ore plant adopted dovetail ZTA tiles for feed chutes; original 92 alumina liners needed full replacement every 3 months, while ZTA tiles stayed intact for more than 7 months. Custom sizes and grooves are available for non-standard equipment.

3. Application Scenarios

This tile series provides heavy anti-impact lining for mines, cement plants, thermal power stations and port bulk delivery systems. It fits large feed hoppers, raw chutes, vertical cyclones and high-load ball mill inner walls under violent lump collision. It can be used alone or paired with composite lining boards to build multi-layer heavy abrasion shielding.

5. FAQ

Q: What raw materials make up ZTA ceramic tiles?A: Alumina-zirconia composite containing 21%-23% zirconia for balanced hardness and impact resistance.

Q: Are these tiles tougher than conventional high-alumina liners?A: Their fracture toughness doubles 95% alumina products and resists breakage from large lump strikes.

Q: Can ZTA ceramic tiles be used in weakly corrosive conveying conditions?A: Dual-phase crystals hold stable chemical inertness, resisting mild acid and alkali without peeling.

Q: Can I customize tile dimensions and groove styles?A: We adjust tile length, width, thickness and dovetail grooves based on your equipment size.

Q: How long will bulk tile orders take to deliver?A: Standard flat and interlock tiles are in stock; bulk goods ship within 7–15 working days post deposit.
