Embodiment 1

[0025] A glass-ceramic bowl with good strength is composed of the following components in parts by weight: 50 parts of silicon dioxide, 18 parts of nano-silicon carbide, 10 parts of aluminum oxide, 5 parts of glass fiber, 0.8 part of chloroplatinic acid, tourmaline 1 part of fine powder, 3 parts of boron nitride, 1 part of sodium silicate, 3 parts of carbon fiber, 0.2 part of selenium powder, 2 parts of firing aid, 0.5 part of graphene microflakes and 0.8 part of boron fiber;

[0026] Graphene microflakes are grown in a three-dimensional honeycomb manner. After generation, wet nano-grinding is used to grind in a single direction to prepare graphene microflakes with nanometer thickness and micron area. All four valence electrons form covalent bonds and are bound, unable to form a directional mobile electron flow, so they cannot conduct electricity.

[0027] A method for preparing a glass-ceramic bowl with good strength, comprising the following process steps,

[0028] 1) Dispe...

Embodiment 2

[0034] A glass-ceramic bowl with good strength is composed of the following components in parts by weight: 55 parts of silicon dioxide, 20 parts of nano-silicon carbide, 15 parts of aluminum oxide, 8 parts of glass fiber, 1 part of platinum compound, and fine powder of tourmaline 1 part, 4 parts of boron nitride, 2 parts of sodium silicate, 4 parts of carbon fiber, 0.5 part of selenium powder, 3 parts of firing aid, 1 part of graphene microchip and 1 part of boron fiber;

[0035] The platinum compound is selected from chloroplatinic acid;

[0036] The graphene microflakes are produced by growing crystals in a three-dimensional honeycomb manner. After generation, wet nanogrinding is used to grind in a single direction to prepare graphene microflakes with a nanometer thickness and a micronized area, in which each carbon The four valence electrons of the atom are all bound by covalent bonds, and cannot form a directional mobile electron flow, so they cannot conduct electricity. ...

Abstract

The invention relates to a glass ceramic bowl with good strength, and relates to the technical field of tableware. The glass ceramic bowl comprises the following components in parts by weight: 50-55 parts of silicon dioxide, 15-20 parts of nanometer silicon carbide, 10-15 parts of aluminium trioxide, 3-8 parts of glass fibers, 0.5-1 part of platinum compounds, 0.5-1 part of tourmaline micropowder, 2-4 parts of boron nitride, 0.2-2 parts of sodium silicate, 2-4 parts of carbon fibers, 0.1-0.5 part of selenium powder, 0.1-1 part of graphene mini-sheets and 0.5-1 part of boron fibers. The glass ceramic bowl disclosed by the invention is smooth in surface, good in strength and low in possibility of breaking due to dropping through special preparation on raw materials. Compared with the traditional process, the glass ceramic bowl disclosed by the invention has the advantages of short required time, low energy consumption, good product texture and no toxic substance residue.

Description

technical field [0001] The invention relates to the technical field of tableware, in particular to a glass ceramic bowl with good strength and a preparation process. Background technique [0002] Glass is divided into non-oxide glass and oxide glass according to the composition, oxide glass is divided into silicate glass, borate glass, phosphate glass and so on. Silicate glass refers to the basic composition of Si0 2 Glass is a colorless and transparent material with the largest output, the widest range of uses, and the lowest price. Quartz glass is the best among silicate glasses. The raw materials used to manufacture quartz glass are crystal, high-purity quartz sand, or white quartz sand, and its composition is high-purity Si0 2 , the melting temperature is required to be above 1713°C. [0003] Quartz glass has a series of special physical and chemical properties: 1. It has excellent high temperature resistance, and its melting point is similar to that of platinum; 2. T...
