Abstract

The invention discloses high-temperature-resistant transparent phosphate glass and a preparation method thereof. The method comprises steps as follows: zinc oxide and water are mixed; ball milling is performed through a planetary ball mill, and a turbid liquid is obtained; a phosphate aqueous solution is dropwise added to the turbid liquid and stirred by a magnetic stirrer; the mixture is dried in a dryer, and solids are obtained; the solids are ground into powder; the powder is pressed to form a block; the block is sintered at the temperature of 1,500 DEG C, and the high-temperature-resistant transparent phosphate glass is prepared. According to the method, the required raw materials are simple and easy to obtain, and the non-uniform phenomenon is not easily caused in the preparation process; the prepared phosphate glass has high transparency, compact structure and high strength.

Description

Technical field [0001] The invention relates to a glass and a preparation method thereof, in particular to a high-temperature resistant phosphate transparent glass and a preparation method thereof. Background technique [0002] Heat-resistant glass is mostly used for utensils, baby bottles, experimental beakers, industrial boiler sight glasses, and window glasses for mechanical equipment. [0003] The heat-resistant glass is mainly quartz glass. Transparent quartz glass can withstand 1100-1200℃ freely, and can also be heated to 1400℃ in a short time. [0004] Quartz glass is the leader in silicate glass. The raw material used in the manufacture of quartz glass is mainly crystal, and its composition is high-purity Si0 2 , But crystal itself is a kind of rare mineral, and its smelting temperature is required to be above 1713℃. The energy consumption is large, and the operation is relatively dangerous. In addition, the melting temperature of silicon oxide is 1713°C and the vaporizati...
