Method for preparing microcrystalline glass heating plate based on in-situ crystallization technology

Abstract

The invention discloses a method for preparing a microcrystalline glass heating plate based on an in-situ crystallization technology and application thereof. The method comprises the following steps of: firstly, modifying 95% alumina ceramic material by adding ions, such as Ba<+> and Si<+> and the like; secondly, compounding the modified alumina ceramic material by processes, such as printing, sintering and the like; thirdly, permanently manufacturing the compounded material and a glass plate into a whole to form an inorganic conductive resistance layer; and finally, electrifying to heat and emit infrared heat energy, forming a heat radiation source and heating in a conduction and convection manner, so as to prepare the advanced microcrystalline glass heating plate. The advanced microcrystalline glass heating plate is practically applied to an electric kettle.

Description

technical field [0001] The invention belongs to the application field of modification technology of microcrystalline nano-ceramic materials, and in particular relates to a preparation method of a microcrystalline glass heating plate based on in-situ crystallization technology. Background technique [0002] In-situ controlled crystallization technology completely solves a series of difficult problems in traditional ceramic material preparation technologies such as the source of ceramic powder, powder agglomeration and dispersion, densification and grain growth during high-temperature sintering, etc. It is a new technology for the preparation of high-performance and low-cost nano-ceramics with the most industrialization prospects. [0003] At present, exquisite, practical, convenient and fast electric kettles have begun to enter thousands of households and become small household appliances for daily life. Statistics show that based on the 30% ownership rate of urban residents...
