Product Introduction

Alumina hollow sphere is a new type of high-temperature insulation material. It is made by smelting and blowing industrial alumina in an electric furnace, and its crystal form is a-Al2O3 microcrystals. With alumina hollow sphere as the main body, it can be made into products of various shapes. The maximum use temperature is 1800℃. The product has high mechanical strength, which is several times that of general lightweight products.

Features

1.Lightweight.
2.Closed cell material.
3.High temperature resistance.

Application

It has been widely used in high temperature and ultra-high temperature furnaces such as petrochemical industry gasification furnaces, carbon black industrial reactors, metallurgical industry induction furnaces, and has achieved very satisfactory energy-saving effects.
