Using dolomite and sinter magnesia clinker as a main material and added with alkali metal phosphate binder and additives,amagnesia-calcia coating material has been developed.
Applying the theory of rheodynamics and hydraulic theory, a relationship of damping vs. vibration velocity, electric field strength and gas-filled pressure has been set up.
The dependences of seepage velocity and bending strength on agglomerant content, forming pressure, particle diameter of the aggregate, soaking time, firing temperature and so on were discussed.
