阅读说明:本技术 利用成核和生长密度以及粘度变化对玻璃进行陶瓷化的方法 (Method for ceramizing glass by using nucleation and growth density and viscosity change ) 是由 C·A·克里克 I·杜塔 O·古比腾 J·M·霍尔 M·G·J·休伯特 A·P·奇托森 于 2019-07-15 设计创作,主要内容包括:将玻璃制品陶瓷化为玻璃陶瓷的方法包括将玻璃制品放入加热设备中,并且以第一预定加热速率将玻璃制品加热至第一保持温度。玻璃制品在第一保持温度下保持第一预定持续时间。在第一预定持续时间内,玻璃制品的粘度保持在对数粘度±1.0泊之内。然后,将玻璃制品以第二预定加热速率从第一保持温度加热至第二保持温度。玻璃制品在第二保持温度下保持第二持续时间。从自第一保持温度加热玻璃制品开始到整个第二持续时间,监测玻璃制品的密度,并且当玻璃制品的密度变化速率的绝对值小于或等于0.10(g/cm~3)/min时,结束第二持续时间。(A method of ceramming a glass article into a glass ceramic includes placing the glass article into a heating apparatus and heating the glass article to a first holding temperature at a first predetermined heating rate. The glass article is held at the first holding temperature for a first predetermined duration. The viscosity of the glass article remains within 1.0 poise of the logarithmic viscosity for a first predetermined duration. The glass article is then heated from the first holding temperature to a second holding temperature at a second predetermined heating rate. The glass article is held at the second holding temperature for a second duration. From a first holding temperatureMonitoring the density of the glass article throughout the second duration from the start of heating the glass article, and when the absolute value of the rate of change of the density of the glass article is less than or equal to 0.10 (g/cm) 3 ) At/min, the second duration ends.)
