Boron carbide material fabricated by carbon-doping activated sintering;

The method of promoting low temperature activated sintering technology of PZT ceramics is introduced in detail from aspects of material-preparing,sintering aids and sintering technics,etc.

The effect of Al on activated sintering of tungsten was studied.

In order to understand more deeply the process of spontaneous combustion of coal,changes of active structures in coal were tested at different temperature points with infrared spectrum analysis.

Based on reaction mechanism, active structure, catalyst preparation and reactive process, this paper reviewed the advances in research on the catalysts used in catalytic reaction of olefin oligomerization both at home and abroad, including solid phosphoric acid, molecular sieve, supported and non-molecular sieve catalysts respectively.

Different active structures need different temperature to activate when coal is oxidized in low- temperature.

This thesis investigates the chemical stability,sinterability,electrochemical performance and the thin-film preparation techniques for the BaCeO_3 based proton-conducting SOFCs.

Preparation of Ni-Cr/BN self-lubricating composites by active sintering process;

Using low melting point pre-alloy powder to which a carbide forming element namely Titanium was introduced as bonding metal, diamond saw segment was prepared by liquid active sintering (LAS) in vacuum furnace.
