Title:
A PLATE COMPRISING AN AMORPHOUS CERAMIC COATING LAYER, ITS USE AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2012/018201
Kind Code:
A2
Abstract:
This invention relates to a plate including an amorphous ceramic coating layer, its use and a method of manufacturing the same. More specifically, this invention relates to plate including an amorphous ceramic coating layer obtained by coating a composition including 24 to 56 parts by weight of silica sol, 11 to 30 parts by weight of alcohol, 0.1 to 0.2 parts by weight of an additive, 0.2 to 27 parts by weight of a filling, 0.5 to 5.0 parts by weight of porous ceramic, and 15 to 32 parts by weight of a hardening agent on the plate, followed by firing at 100 to 350℃ and cooling at 10~30℃/sec. The plate including the amorphous ceramic coating layer of this invention has an enhanced durability due to very high improvement of mechanical properties such as abrasion resistance, corrosion resistance, and heat resistance. Also, the plate of this invention has no occurrence of cracks, barely exhibition of brittleness even at an excessive stress, and a hardness increase to the level of twice to three times higher than a conventional ceramic coating layer, which is similar to that of enamel. Furthermore, when multi-layered coating with more than two layers is rapidly cooled or ultra-rapidly cooled, a completed ceramic coating film with a high physical property, no cracksand no peeling shows an electrically semiconductor characteristic due to the amorphous ceramic.
