摘要

Vaterite is a crystal polymorph of calcium carbonate that is widely used in various industries, but rarely occurs in nature. This article presents an effective method for application of vaterite-type calcium carbonate as a coating pigment for ink jet paper instead of silica. Vaterite was prepared by mixing and agitating K_2CO-3 and CaCI_2 solutions with an ultrasonic homogenizer. The vaterite crystal stability was examined to achieve vaterite properties appropriate for ink jet application. A high pH reduced transformation from vaterite to calcite because of the low solubility constant. Experiments revealed a low water contact angle on our vaterite-coated paper, suggesting high ink jet print quality. Furthermore, although our test calcite-coated and silica-coated samples exhibited bleeding, our vaterite-coated samples matched commercial silica-coated samples in quality, probably, because the large hydrophilicity of vaterite promoted quick inward absorption of inks before they could spread laterally on the surface.
