◆ Product Introduction

Sintered Alumina appears white granular or powder and is produced from grinding alumina powder under high temperature calcination and shaping. It features high purity, complete crystallization,reliable thermal shock performance.

Refractories with our products enjoy advanage of anti-erosion, scouring resistance, and long service. Thanks to these advantages, our product not only find its application in refactories and abrasive industries but it also serves in metallurgy,ceramics,construction etc which are high temperature operation industries as premium raw materials solutions.


Q: Our brand history about Sintered Alumina.

A: TBL,a leading brand in China for Sintered Alumina supply.It’s the star branch company in our group. Since its establishment, Mr.Zhang Huiyou,who is respected as The Father of Chinese Sintered Alumina.

In 1995, jinan pingyin lu nai new material factory, founded by zhang huiyou as the technical director, approved the project of "Sintered Alumina" by jinan science and technology commission, and started construction in July of that year. In order to develop national industry and break the foreign monopoly on products, we use industrial grade alumina as raw material, in order to produce the high-quality and cheap board corundum products that can afford by the material resistant enterprises. In June 1996, the factory used advanced technologies such as large ceramic liner mill and ultra-high temperature shaft kiln to achieve the success of industrial production of Sintered Alumina.
