Applications of molybdenum disilicide heating elements in the high-temperature glass industry.
2025-09-23
Why is it much more difficult to make a heat-resistant glass cup than an ordinary glass cup? The key lies in the process temperature.
When we talk about "high-temperature glass", borosilicate glass (such as the well-known PYREX®) is often the model. One of the core differences between it and ordinary soda-lime glass lies in the process temperature, which directly affects your choice of heating elements.
Discussions with some manufacturers of high-temperature glass:
1:Higher energy consumption: The melting and forming of borosilicate glass needs to be continuously maintained above 1200°C, which poses severe challenges to the long-term high temperature resistance and oxidation resistance of the heating elements.
2:Strict temperature uniformity: The narrow processing window requires that the entire thermal field must be extremely uniform. Any slight temperature fluctuation may cause stress, streaks or deformation on the product.
3:Component life is profit: At such high temperatures, ordinary heating elements will quickly age and fail, resulting in frequent production stoppages and replacements, and a sharp increase in production costs.
Our molybdenum disilicide (MoSi₂) /SIC heating elements, designed for oxidizing atmospheres up to 1800°C/1600°C, are ideal for meeting these challenges. They provide a stable heat field in this range, and their excellent heat resistance ensures a longer service life, ultimately helping you reduce energy consumption and maintenance costs.
What is the biggest temperature control challenge in your high-temperature glass production process? Component lifespan or thermal field uniformity?
