Latest Patents

One of Yuji Baba's latest patents is for a quartz glass crucible that features a unique design comprising a bottom portion, a curved portion, and a straight body portion. This crucible includes an outer layer made of opaque quartz glass containing bubbles, and an inner layer of transparent quartz glass. The outer layer is designed with multiple layers in part of the straight body portion, where one layer exhibits a devitrification spot number of 50/cm or more and 70/cm or less when heated at 1600°C for 24 hours. Additionally, a layer positioned inward of the devitrifiable layer is a low devitrification layer with a spot number of 2/cm or less under the same heating conditions. This innovative design helps to suppress deformation due to heating and excessive devitrification progression.

Another patent by Yuji Baba involves a quartz glass crucible and a method for producing the same. This crucible also consists of bottom, curved, and straight body portions, with an outer layer of opaque quartz glass containing bubbles and an inner layer of transparent quartz glass. The outer layer is fabricated from different types of raw material powder, and it features regions sectioned by bubble content densities. The difference in content densities between two adjacent regions is defined as 10% or more, enhancing the performance of the crucible during use.
