VINER Industrial Ceramic Alumina Crucible Typica Application:
Ceramic Alumina ceramics with superior strength, hardness, insulation, thermal conductivity, high temperature, oxidation resistance, corrosion resistance, abrasion resistance, high temperature strength and other characteristics, it has been widely used in engineering, mechanical seals, electronics, instrumentation, sensing, transport, communications, and other occasions or areas.

The content of 99.7%, 99%, 95% alumina products contains the crucible, sockets, valves, electrodes, spools, wear board, alumina balls, electronic porcelain, textile porcelain pieces, and other shaped pieces.

Notice for Using VINER Industrial Ceramic Alumina Crucible:
1. Alumina products are fragile. Please handle them carefully and avoid collision during unpacking, transportation, handling and cleaning
2. Check whether any micro-cracks exist before using alumina products. Products with micro-cracks should not be used.
3. Alumina products should be completely dry before usage. If they get wet, let the crucible or tube dry naturally before using them. If dry crucibles by placing in a dryer or oven, make sure that the dry process goes slowly.
4. Do not load too many materials in alumina crucibles, which can increase the possibility of uneven heating.
5. Alumina crucibles are sensitive to thermal shock. Try to warm up the furnace chamber slowly. A heating rate of 150C/hour is recommended for the first 1-1.5 hours so that the crucibles can be evenly heated to reduce the impact of thermal shock. It usually takes about 3 hours to increase to high temperature.
