The volume expansion of hydrogen absorption and hydride thermostability of Ti 87.

Thermal expansion actuated characteristics of paraffin were tested on apparatus heated by water bath and the relationship of volume expansion vs.

This paper analyses main reasons about volume expansion of circulating solution during recovery of mercury from gas for acid-making using iodo-mercury compounding method,points out some problems arising in the way for coping with the volume expansion and proposes a new method which is simple, feasible and effective.

The study of the quantitative contribution of the thermal volume expansion to the positive temperature coefficient (PTC) switch effect of fine particles filled polymer composites in the carbon black polyethylene(CB PE) system is reported.

When meet with water,some reactions of the f-CaO in cement based material will happen and great deal of heat will be produced,and the outcome will result in volume expansion and bad soundness,even so these performance of f-CaO can be utilized.

The effect of reaction temperature,time,expanding temperature on the expanded volume was discussed here.
