Details
Product Characteristics:
The granulated powder has high purity, large bulk density, excellent sphericity, uniform particle distribution, good fluidity, and is easy to form and demold by dry pressing. The green body has high density and strong bonding force. It exhibits excellent low-temperature firing performance, resulting in small crystal nucleus size, low porosity, high ceramic density, and low shrinkage rate after firing, with superior structural and mechanical properties.
