Effects of Si3N4 Additions on Creep Resistance of Al-Al2O3 Composites Haoning Shia, Yong Lib, Chuanjing Li, Haixia Qin and Jialin Sun School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China anjdexy@163.com, blirefractory@vip.sina.com(corresponding author) Keywords: Silicon nitride; Creep; Aluminum; Alumina Abstract.
The result indicates that the change of interior material has occurred, causing creep resistance of sample increased.
Grain boundary phase and microstructure of the material determines its creep properties [8-9].
Slip along the direction of crystal and particle diffusion along grain boundaries led likely to pure corundum materials poor creep resistance.

Introduction White mineral fillers are widely used in rubber, paint and other polymer materials.
Coating nanometer CaCO3 particles on the mineral particles,changing the surface properties of micron powder,the smooth cleavage surface becomes rough, its sharp edges will be passivated, the binding force between the filler and polymer materials will be effectively increased, the problem of composite local stress concentration will be solved,so the advantages of nanoparticles will be effectively used and high performance composite materials will be obtained while reducing the cost of production.
This may be because part of the Ca(OH)2 was coated on the mineral particle surface without reacting with CO2, or because of any other loss of material.
