Abstract

The invention provides a method for producing black transparent microcrystal glass and its products, wherein the base glass comprises Li2O, RO, Al2O3 and SiO2, the coloring agent comprises NiO, V2O5 and Fe2O3, the crystal nucleus agent comprises TiO2, Zr2O5 and P2O5, the weight percentage of each component being, Li2O: 2.5-4.7%, RO: 2-3%, Al2O3: 17-26%, SiO2: 62-72%, NiO: 0.05-0.1%, V2O5: 0.1-0.2%, Fe2O3: 0.05-0.1%, TiO2: 2-2.5%, ZrO2: 1.5-2.5%, P2O5: 1-2%. The formulation and related die arrangement can be used for making electromagnetic oven plate, disc, microwave oven disc, roasting and grilling plate, baking oven cloche, frying pan and various pots.

Description

Technical field: [0001] The present invention relates to Li 2 O-Al 2 o 3 -SiO 2 The composition of black transparent glass-ceramic and the production method of its products. Background technique: [0002] There are many types of glass-ceramics, and glass products for different purposes can be produced by different composition ratios and different processes. Most of the glass-ceramics disclosed in the patent literature are architectural decorative materials such as wall tiles, or handicraft products. At present, various heating products produced by glass-ceramics have not been found in the market, such as heating plates, pans, grilling plates, frying pans, etc. for induction cookers, microwave ovens, Yale stoves, gas stoves, etc. its related content. Invention content: [0003] The purpose of the present invention is to improve the existing glass-ceramic formula, and to provide a heating plate, pan, frying pan, frying pan and various heat-resistant pots suitable for i...
