Name: Tube Furnace (1700-100-290)
Brand: Canrud

Question 1

Accepted Answer

Press the dry powder into green bodies in a steel die at 250–500 MPa, cover with parent powder, sinter in an argon-atmosphere furnace at 1200°C for 2 h, then grind the sintered plates.

Question 2

Accepted Answer

We are very sorry — we really do not know the sintering conditions. Different companies have different sintering conditions, and these process parameters are kept confidential by the companies. A tubular furnace at 900°C for 10 h with atmosphere control is provided to the customer as a reference; oxygen atmosphere control is required.

Question 3

Accepted Answer

It’s best not to use graphite crucibles or graphite-lined furnaces. During the sintering of lithium-ion solid electrolyte pellets, lithium volatilization occurs; the exact species are unclear, and the volatiles can affect the furnace. The same applies to crucibles—the lithium volatiles can reduce crucible lifespan. Graphite crucibles may also contaminate the material, and atmosphere control during sintering would need to be more stringent. Commonly used crucible materials are platinum, alumina, and magnesia.

Question 4

Accepted Answer

[Powder Pressing Method] Dry powder is placed into a steel die and pressed at 250–500 MPa to form a green body, then sintered in a muffle furnace in air atmosphere at about 900°C for 3–24 hours. After sintering and cooling, the ceramic discs are ground. The green body pressing may include a binder or not, and may include a sintering aid or not. Binders used include PVA, PVB, etc.; sintering aids include boron oxide, lithium borate, and similar. Note that if a binder is added, the sintering must be staged to allow binder burn-out; otherwise the carbon content will be too high.

Question 5

Accepted Answer

According to the knowledge base, official website may have a "soft pack battery line" suitable for soft pack battery testing, which may include a line connecting two clips with one head, but the specific name needs further confirmation.
