2300C High Temperature Vacuum Tungsten Sintering Furnace

Introduction

QSH-SZW series vacuum tungsten furnace is a periodic operating furnace. Its interior is carbon-free, eliminating carbon contamination. It is suitable for sintering and degassing high-purity ceramics into transparent ceramics, tungsten electrodes, and other materials under high vacuum, as well as vacuum sintering of tungsten and molybdenum products. It is mainly used for melting and sintering high-melting-point metals, alloys, ceramics, and other materials. It can also be used for bright annealing and degassing of some metals, or for measuring the physical and chemical properties of metals, ceramics, etc., under high-temperature vacuum conditions.
