Electroceramics. Titanates like barium, strontium, calcium and lead titanate prepared from finely divided, high-purity TiOz hydrolysates are used in capacitors, PTC-resistors and piezoelectric materials. The specifications of the Ti02 starting materials with respect to purity, reactivity, and sintering properties are expected to become more stringent. The market is estimated to be several thousand of tonnes a year as TiOz. A strong annual growth is expected.

The manufacture of cubic p-SiC, which is favored at temperatures below 2000°C, or mixtures of a- and p-SiC is carried out by deposition from the gas phase (Chemical Vapor Deposition). p-SiC powder with good sintering properties and small crystallite size is e.g. obtained by the thermal decomposition of alkyl silanes or alkyl dichlorosilanes in plasmas or flow reactors at temperatures above 1000°C ... 

Particle size distribution measurements should also be made from lab milled samples only. The particle size distribution influences the compacting behavior and green density as well as the sintering properties. 

In spite of its limitations, the linear standard B.E.T. equation (Equation 627) is widely used to determine the surface areas of adsorbents. Specific surface area is often correlated with rates of dissolution and other rate-related phenomena, such as catalyst activity, electrostatic properties of powders, light scattering, opacity, sintering properties, glazing, moisture retention, shelf-life and many other properties that can influence the processing and behavior of powders and porous solids in industry. Therefore, surface area measurement is probably the most widely used means of characterizing porous materials. Since the surface area corresponds to the roughness of the particle exterior and its porous interior, gas adsorption is the preferred technique. 

Dwell time is necessary to obtain even compaction of the resin in the preform. Insufficient dwell leads to density gradients in the billet, houiglassing which refers to the shape of the billet after sintering, property variation, air entrapment, and microcracks.
