Vycor - Wikipedia
Vycor is the brand name of Corning's high-silica, high-temperature glass. It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide , but unlike pure fused silica , it can be readily manufactured in a variety of shapes.

高硅氧玻璃 - 百度百科
高硅氧玻璃是利用图1 SiO2-B2O3-Na2O玻璃组成的B区易于 分相 的特点来制造的。 首先选取B区域中适当组成,按一般玻璃生产方法制出 半成品。 而后将其在600℃左右 热处理 几个小时,使其分相。 分相后这种玻璃就分离为高Na2O-B2O3相和高SiO2相。 两相分离后每一相的 富集 区都很小,仅有几 埃 至几十埃。 玻璃分相后经 退火 处理,而后用酸溶液与Na2O-B2O3相反应。 反应产生的生成物用 弱碱 和清水洗去。 此时制品就成为高SiO2相的多孔质玻璃了。 此后再 …

2018年4月17日 · A blend of 96% silica and 4% boron trioxide, Corning® Vycor® Glass is a high-temperature glass valued for its low coefficient of thermal expansion — 7.5 x 10-7/°C when measured between 0 °C (32 °F) and 300 °C (572 °F). It also features excellent thermal shock resistance and superior optical qualities.
VYCOR® Code 7913 | Heat resistant 96% silica glass
Excellent temperature resistance allows the use of this glass at high continuous operating temperatures of up to 900 °C. The 96% portion of SiO2 in the glass composition results in a low thermal expansion coefficient and high thermal shock resistance.
