Intermediate-Stage Sintering of a Homogeneously Packed Compact

Several characteristic equations in intermediate sintering dependent on a grain-growth mechanism were quantitatively estimated using the microstructural data of sintered compacts. The relations which were calculated with a computer based on many assumptions described well the changes of a pore-size distribution, of an average radius of grains, and of a specific surface area of an easily sinterable alumina during the sintering. The reasonableness of these assumptions is discussed.
