Manufacturing of irregularly shaped articles based on customer’s blueprints and models
Our quartz ceramic crucibles are ideal for melting pure metals, alloys and dental materials:
• Inertness – no reaction with melts upon heating and no melt composition variation.
• No carburization of materials. Actual melt lost.
• Heat resistance – can withstand thermal shock up to 1700 °С.
• Low coefficient of thermal expansion – non-existent change in shape and size of crucibles upon heating.
Quartz ceramics are characterized by:
The bending strength is 15-45MPa, apparent density is 1.9-2.0 g/cm, the open porosity is 5-15%, the coefficient of thermal linear expansion is 5.8*10-7, heat resistance at a temperature drop of 20-1650 °С, resistance to glass transition in slightly alkaline fluxes.
The material has a high diffuse reflectivity in a wide-spectral region and is resistant to UV radiation. The coefficient of thermal conductivity is 0.6-0.9 kcal / m * h * d, the dielectric constant at a frequency of 10 * 10 Hz is 3.2-3,6 in the temperature range of 20-1650 oC. Without temperature changes, the material can withstand heating and utilization at temperatures up to 1700 oC.
