[0002] The research on the preparation of building ceramics by sintering lithium tailings has gradually attracted attention in recent years, especially in terms of resource recovery and ecological protection. The main components of lithium tailings include minerals such as silicon, aluminum, and iron, which are common materials for preparing building ceramics. The use of lithium tailings for the preparation of building ceramics includes but is not limited to the following benefits: 1. Low toxicity. Compared with other industrial wastes, lithium tailings have less impact on the environment and are safer to use; 2. High stability. The mineral components in lithium tailings have good stability during high-temperature sintering, which will increase the strength of the fired ceramics; 3. Reduction in production costs. Using lithium tailings as a raw material for ceramics can reduce the cost of preparing building ceramics and improve economic benefits.

This will result in the difficulty in accurately controlling the performance of the sintered building ceramics during the sintering process. Not only will the qualified rate of the sintered building ceramics decrease, it may even cause large batches of building ceramics to fail, resulting in serious product performance problems and causing huge losses.
