ABSTRACT:
An improved flexible ceramic tape consists essentially of ceramic powder and a water soluble binder of polyacrylic acid polymer and glycerol. Additions of small amounts of polyvinyl pyrrolidine to this binder improves the flexibility of the resulting tape. The ceramic powder consists of alumina. The invention also comprehends the method of making this tape consisting of the steps of preparing a slip or mixture of an aqueous solution of polyacrylic acid polymer and glycerol together with the ceramic powder, casting this slip on a substrate to a predetermined uniform thickness, and drying the mixture. The tape may be removed from the substrate or allowed to remain mounted on it.
