solid-state preparation at low heat的用法和样例：
- solid state reaction at low heating temperature
- Superheat decreases as the channel narrows at low heat flux, but it inverts at high heat flux.
- Earthenware: Pottery that has been fired at low heat and is slightly more porous and coarser than stoneware and porcelain.
- Preparation of nanoparticle CdS by solid state reaction at low temperature
- The films prepared at low voltage lighten by UV also show good bioactivity after soaked in simulated body fluid（SBF）.
