High-Purity Low-Temperature Sinterable Alumina Ceramic granulated powder Series
This granulated powder covers full purity grades from 99.9% to 99.99%, with high tap density, excellent sphericity, uniform particle distribution and superior flowability. It enables easy dry pressing and demolding, delivering high green density, low sintering shrinkage. It boasts outstanding low-temperature firing performance, yielding sintered products with fine crystal nuclei and low porosity after firing.
Product Introduction

This granulated powder features high-purity, high tap density, good sphericity, even particle distribution and favorable flowability. It supports easy dry pressing and demolding, producing dense green bodies with strong bonding strength. It exhibits excellent low-temperature firing characteristics. Post-sintering products feature tiny crystal nuclei, low porosity, high ceramic density and low shrinkage rate, delivering exceptional structural mechanical properties.
