Glass Crystallization Test Furnace
Published: 8/12/2016
The GXT Glass Crystallization Test Furnace evaluates the crystallization tendency of glass and other non-metallic materials using a controlled temperature gradient. It supports laboratory and industrial R&D to define melting, forming, and heat-treatment regimes that minimize devitrification.
Product Description
The GXT Glass Crystallization Test Furnace applies the gradient-furnace method to determine the crystallization behavior of glass, including the effective temperature range and degree of crystallization. By exposing samples to a defined gradient from the low-temperature end and observing structural changes, users can assess devitrification risks and optimize processing conditions.
Designed for factories, universities, and research institutes, the system provides a long alumina tube hot zone and adjustable heating rates to replicate practical thermal histories. Results guide the formulation, forming, and thermal processing of glass and similar non-metallic materials to achieve transparent, defect-free products.
