Product Description

ZALY alumina powder

Activated alumina powder-Alpha alumina-Reactive alumina

ModelAl2O3 ≥ %Na2O ≤ %Fe2O3 ≤ %SiO2 ≤ %True Density g/cm3α -Al2O3≥ % D50 um
TCH -5H990.150.020.153.9595≤ 1
TCH-5L99.50.150.020.153.9393 ≤ 0.8

Good chemical activity
Fine grain
High conversion rate
Low water absorption

We produced α -Al2O3 by ultra-low temperature conversion calcining process. It is mainly used for iron groove castables, refractory castables for ladles etc. Pouring fever layer is very compact, good permeability, and low erosion rate.

Zaly-calcined alumina features:

*Production process: Traditional Bayer process
*High alumina, low sodium
*1-75um powder (200 mesh, 325 mesh, 1000mesh etc)
*High density 3.95g/cm3
*1450° C high temperature calcined
*Stable quality control
*Factory located in import-export tax free area, price is best.

Application:
*Wear resistant ceramic, electronic ceramics, small ceramic parts.
*Refractory- - Shaped refractory (firebrick etc) & Unshaped refractory (castable etc)
*glaze series.

ZALY's alumina suitable for dry pressing, CIP, injection moulding etc.
