IPC: B41J2/335
Filed: 1990-07-17
Abstract: PURPOSE:To obtain rapid printing and high density processes by forming a heat-resistant glazed layer at an area from which a vitreous flux agent is removed on the surface of an alumina substrate consisting of alumina of a specified purity. CONSTITUTION:A heat-resistant glazed layer 12 having a glass transition point of 700 deg.C or higher is formed on an alumina substrate containing a vitreous flux agent in alumina of 99% or higher purity. Thus a thermal head substrate is composed of these alumina substrate 11 and heat-resistant glazed layer 12. The alumina substrate 11 is soaked in a fluorine etching agent, i.e. a fluoric- nitric acid obtained by blending HF, HNO3 and H2O to remove the vitreous flux agent from the surface. This is because of the necessity to fire the heat- resistant glazed layer 12 on the alumina substrate 11 from which the vitreous flux agent is removed for preventing the generation of bubbles.
