Product Description
The crucible with alumina content above 95%, (shape: square, cylindrical, arc) can be used at a temperature of 1600 degrees, suitable for various laboratories, testing centers, analysis of metal and non-metal samples and other industrial analysis.
- Good chemical corrosion resistance.
- Good temperature resistance, long-term use at 1600°C, short-term use at 1800°C.
- Good resistance to rapid cooling and heat, not easy to burst.
- High density of grouting molding.
L.T Group has a comprehensive product and technology portfolio that focuses on four field of graphite - ultrafine particle graphite mould,graphite electrode, graphite crucible, as well as other products mainly made of graphite.
Graphite materials exhibit unique properties such as good electrical and thermal conductivity, heat and corrosion resistance, low friction, and reduced weight while at the same time maintaining high strength. Due to the shortage of energy and raw materials, our high performance products made from graphite are in increasingly high demand in industries. They also play a progressively important role in everyday life, thereby substituting traditional materials
1. Cleaning: Soak in nitric acid for a long time; then wash with water.
2. Dry moisture: The corundum crucible should be dried before use to prevent bursting caused by water. It is usually dried at a temperature of about 200 degrees, and the temperature is slowly raised to 800 degrees in a high-temperature furnace for 6 hours. Use after cooling.
3. Remove impurities: convert insoluble matter into soluble nitrate and remove
Remove trace nitrates in the crucible (thermal decomposition method): Note that the heating rate must not be fast, otherwise the crucible will be skinned (explosive damage).
4. Try to heat up as slowly as possible, and cool down as slowly as possible, the speed of heating and cooling has a great impact on the service life of the crucible.
5. The corundum crucible is suitable for melting samples with some weak alkaline substances such as anhydrous Na2C03 as flux, but not suitable for melting samples with strong alkaline substances such as Na 202 and NaOH and acidic substances (such as K2S 207, etc.)

Company Profile
L. T GROUP is formally authorized by Industrial and Commercial Bureau of China. We have two main product lines: Construction materials (mainly concrete and terrazzo); Another is Carbon and Graphite industry.
L. T Graphite (ltgraphite. COM): Graphite materials exhibit unique properties such as good electrical and thermal conductivity, heat and corrosion resistance, low friction, and reduced weight while at the same time maintaining high strength. Our tech team are exploring more possibilities for carbon graphite application together with customers.
L. T Terrazo (ltterrazzo. COM): Terrazzo is an excellent building material. It is environmentally friendly, easy to maintain, non-slip, and multiple designs available. In this field, we are constantly improving the production process to break through many restrictions on concrete artificial stone. The product quality is high-end and stable now. For floor series, we developed big slab, raised floor series; For decoration furniture series, we developed desk-top, whole-body "L"stairs, which are all leading technology in this field.
L. T people should think about these issues and create a better world through continuous struggle from generation to generation. At present is embodied in 3 aspects:
1. Based on the premise of environmental protection, technological innovation of production process to improve the efficiency of the use of limited resources
2. Continuous exploration in the field of new energy.
3. Start with the improvement of the human settlement environment, and cooperate with the terminal enterprises and end users to explore the multiple values of our products.
