Importance Factor for Synthesis Original Compound (Na,K)₂CO₃ of New Type BLSF Lead-Free Ceramics (Na,K)₂Bi₆Ti₇O₂₄

New type BLSF ceramics (Na,K)₂Bi₆Ti₇O₂₄ (NKBT) were safely and environmental protection lead-free material. The dielectric constant of 30, and tanδ=2.3%.This study manufactured original compound material (Na,K)₂CO₃ of NKBT, successfully. New type BLSF ceramics NKBT were yet produced a successfulin the past. After a series of efficient and accurate results showed keys of successfully producing NKBT is synthesis of sodium carbonate and potassium carbonate prior to original compound-(Na,K)₂CO₃. Chloride anion(Cl^-) in water, shear force by mixing and drying temperature are the keys to a successful factor. In this paper, we get optimal (Na,K)₂CO₃ powder by rotation velocity 300 rpm and drying temperature 110°C. (Na,K)₂CO₃ powder had the advantageof uneasy deliquesce, manufacturing process easy,fast and low working temperature because of using integration and synthesis of carbonic oxide and there was clear evidence of (Na,K)₂CO₃ by scientific instruments as Scanning Electron Microscope (SEM) etc.
