The SBIR research addresses a new technique for improving the working properties of water-based ceramic formulations and the production yields for objects manufactured from these materials. This extensively used class of materials is employed in applications ranging from ceramic substrates to bathroom fixtures to monolithic insulators used for high voltage transmission lines. While many additives have been used to improve the handling properties of clays, the losses due to cracking of large ceramic objects during drying remain at a very high level. Recently, a new additive has been invented which has been proven by our pilot studies to greatly increase the rate and uniformity of drying of certain water-based clays used for decorative ceramics. However, virtually nothing is known about the mechanism by which this additive works nor how to successfully apply it to ceramics of industrial important. Therefore, a scientific study is planned to explore the interaction of this new additive with water-based clays and to develop a model of this mechanism. The model will then be used to guide the experimental work needed to successfully use this additive with selected ceramics with large commercial markets.

SBIR 研究提出了一种新技术，可提高水基陶瓷配方的工作性能以及由这些材料制造的物体的产量。 这种广泛使用的材料类别广泛应用于从陶瓷基板到浴室装置再到用于高压输电线路的整体绝缘体。 虽然许多添加剂已被用来改善粘土的处理性能，但由于大型陶瓷物体在干燥过程中破裂而造成的损失仍然处于非常高的水平。 最近，我们发明了一种新的添加剂，经我们的试点研究证明，它可以大大提高某些用于装饰陶瓷的水基粘土的干燥速度和均匀性。 然而，实际上人们对这种添加剂的作用机制以及如何成功地将其应用于重要工业陶瓷一无所知。 因此，计划进行一项科学研究来探索这种新型添加剂与水基粘土的相互作用，并开发这种机制的模型。 然后，该模型将用于指导成功地将这种添加剂与具有大型商业市场的选定陶瓷结合使用所需的实验工作。
