Abstract

The invention belongs to the field of glass, and discloses glass ceramics by taking stone powder as a raw material and preparation method thereof. The glass ceramics by taking stone powder as the rawmaterial comprise the components in parts by weight: 40-50 parts of stone powder, 35-45 parts of quartz sand, 3-5 parts of sodium carbonate, 3-5 parts of potassium carbonate, 4-6 parts of spodumene, 2-4 parts of bismuth oxide, 3-5 parts of potassium oxide, 2-4 parts of zinc oxide and 1-2 parts of zirconium dioxide. The glass ceramics by taking the stone powder as the raw material is tailings and wastes of stone mining factories and stone processing factories, are low in cost, the raw materials such as quartz sand, spodumene, bismuth oxide, potassium oxide, zinc oxide are added in a matched mode, the gradient cooling annealing and gradient heating crystallization preparation process is adopted, and the obtained glass ceramics are high in impact toughness, fracture resistance and compressivestrength, high in machining forming performance, beneficial to development of circular economy, capable of turning waste into wealth and capable of reducing environmental pollution.

Description

technical field [0001] The invention relates to the field of glass, in particular to a crystallized glass using stone powder as a raw material and a preparation method thereof. Background technique [0002] Glass-ceramic, also known as glass-ceramic, is a new type of material developed by combining glass and ceramic technology. Melting takes place to form the base glass. Due to the extremely fast cooling speed, this kind of glass is almost entirely amorphous. Due to its excellent thermal stability, chemical stability, mechanical properties and other characteristics, it is widely used in the fields of electronics, chemical industry, military, aerospace, nuclear industry and construction. . [0003] However, the cost of raw materials for existing glass batches is high, the content of chemical raw materials is high, and the melting temperature of glass is generally between 1600-1650 °C, which will inevitably increase fuel consumption and intensify the erosion of glass liquid ...
