<p>PURPOSE: To realize uniform and stable glass coating at a low cost by mixing and thermally treating glass granulated powder and a chip-type ceramic electronic component for performing glass coating for a surface of a chip-type ceramic electronic component. CONSTITUTION: Polyvinyl alcohol is added to borosilicate zinc glass powder as binder by 2 to 10wt.%. After pure water is added thereto and mixed, it is dehydrated, dried and granulated. Barreling is performed for a sintered body of a chip-type varistor 6 and glass granulated powder 5 is added in a range of 0.1 to 2wt.% to a weight of a sintered body. After well mixed, it is put in an alumina magnetic pot 1 of a heat resistant container. Heat treatment is carried out at about 600 to 800 deg.C while the alumina magnetic pot 1 is rotated.</p> |
