The Influence of Water Present in the Batch on the Fining Process of Lead Crystal Containing More than 24 % by Weight of PbO

Abstract:

The paper deals with the effect of chemically and physically bonded water in the batch on the fining process of lead crystal containing more than 24 wt% of PbO.The influence of water contained in the batch that affects eventually the water content in the glass melt was investigated under laboratory conditions from the viewpoint of its effect on the total degree of fining, the surface tension and the glass viscosity. The role of K2O-containing raw materials characterized by different contents in chemically bonded water as well as the effect of various water contents used for physical batch wetting on above mentioned parameters are discussed by taking into account the production economy and the protection of the environment at the same time.
